  1. * Changes in Quagga 0.99.10
  2. - [bgpd] 4-byte AS support added
  3. - [bgpd] MRT format changes to version 2. Those relying on
  4. bgpd MRT table dumps may need to update their tools.
  5. - [bgpd] Added new route-map set statement: "as-path exclude"
  6. - Zebra RIB updates queue has evolved into a multi-level
  7. structure to address RIB consistency issues.
  8. * Changes in Quagga 0.99.2
  9. - [bgpd] Work queues added to bgpd to split up update processing,
  10. particularly beneficial when a peer session goes down. AS_PATH
  11. parsing rewritten to be clearer, more robust and ready for 4-byte.
  12. - [ripd] Simple authentication is no longer the default authentication
  13. mode for ripd. The default is now no-authentication. Any setups which
  14. used simple authentication will probably need to update their
  15. configuration manually.
  16. - [ospfd] 1s dead-interval with sub-second Hellos feature added.
  17. SPF timers now specified in milliseconds, and with adaptive
  18. hold-time support. RFC3137 Stub-router support added. Default ABR
  19. type is now 'cisco'.
  20. - Solaris least privileges support added.
  21. * Changes in Quagga 0.99.1
  22. - Zserv is now buffered via threads and non-blocking in most cases for both
  23. clients and zebra, which should improve responsiveness of daemons when
  24. they must send many messages to zebra.
  25. - 'show thread cpu' now displays both cpu+system and wall-clock time,
  26. where getrusage() is available.
  27. - Background threads added and workqueue API added, with a
  28. 'show work-queues' command. Thread scheduling improved slightly.
  29. - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
  30. the zebra daemon vty.
  31. - Support for interface renaming on Linux netlink systems.
  32. - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
  33. route-source" command.
  34. - Automatic logging of backtraces should daemons crash to assist in
  35. diagnosis. See the documentation for more information on configuring
  36. logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
  37. * Changes in Quagga 0.98.0
  38. - Logging facilities upgraded. One can now specify a severity level
  39. for each logging destination. And a new "show logging" command gives
  40. thorough information on the current logging system configuration.
  41. - Watchquagga daemon added. This is not well tested yet. Please try
  42. monitor mode first before enabling restart features. It is important
  43. to make sure that the various timers are configured with appropriate
  44. values for your site.
  45. - BGP route-server support added. See the texinfo documentation.
  46. - OSPF API initialisation is disabled by default even if compiled in. You
  47. can enable it with -a/--apiserver command line switch.
  48. - "write-config integrated" vtysh command replaced with "service
  49. integrated-vtysh-config" command.
  50. - Router id is now handled by zebra daemon and all daemons receive changes
  51. from it. Router id can be overriden in daemons' configurations of course.
  52. To fix common router id in zebra daemon you can either install non-127
  53. address on loopback or use "router-id x.x.x.x" command.
  54. - "secondary" keyword is removed from ip address configuration. All
  55. supported OS'es have their own vision what's secondary address and
  56. how to handle it.
  57. - Zebra no longer enables forwarding by default. If you rely on zebra to
  58. enable forwarding make sure to add '<ip|ip6> forwarding' statements
  59. to your zebra configuration file.
  60. - All libraries are built and used shared, on platforms where libtool
  61. supports shared libraries.
  62. - Router advertisement syntax is changed. In usual cases (if you didn't do
  63. any fancy stuff) it's enough to change lines in configuration from:
  64. "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
  65. to:
  66. "ipv6 nd prefix X:X:X:X::/X"
  67. All router advertisement options are documented in texi documentation.
  68. - --enable-nssa configure switch is removed. NSSA support is stable enough.
  69. - Daemons don't look at current directory for config file any more.
  70. * Changes in Quagga 0.96.5
  71. - include files are installed in $(prefix)/include/quagga. Programs
  72. building against these includes should -I$(prefix)/include and e.g.
  73. #include <quagga/routemap.h>
  74. - New option --enable-exampledir puts example files in a separate
  75. directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
  76. compliance.
  77. - New configure options --enable-configfile-mask and
  78. --enable-logfile-mask to set umask values for config and log
  79. values. Masks default to 0600, matching previous behavior.
  80. - Import current CVS isisd from SourceForge, then merge it with
  81. the Quagga's Framework.
  82. * Changes in Quagga 0.96.4
  83. - Further fixes to ospfd, some relating to the PtP revert. Interface
  84. lookups should be a lot more robust now.
  85. - Fix for a remote triggerable crash in vty layer.
  86. - Improvements to ripd, and addition of split horizon support.
  87. - Improved bgpd table support, now dumps at time of day intervals rather
  88. than time from startup intervals. Much improved support for IPv6 table
  89. dumps. show commands for views improved.
  90. * Changes in Quagga 0.96.3
  91. - revert the 'generic PtP' patch. Means Quagga will no longer work with
  92. FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
  93. which the PtP patch introduced.
  94. * Changes in Quagga 0.96.2
  95. - Fix crash in ospfd
  96. * Changes in Quagga 0.96.1
  97. - Iron out problem with the privileges definitions
  98. * Changes in Quagga 0.96
  99. - Privilege support, daemons now run with the minimal privileges needed, see
  100. the documentation for details.
  101. - NSSA ABR support in ospfd.
  102. - OSPF-API support merged in.
  103. - 6WIND patch merged in.
  104. * Changes in zebra-0.93
  105. * Changes in bgpd
  106. ** Configuration is changed to new format.
  107. * Changes in ospfd
  108. ** Crush bugs which reported on Zebra ML is fixed.

  117. nexthop-self
  118. route-reflector-client
  119. route-server-client
  120. soft-reconfiguration inbound
  121. * Changes in zebra
  122. ** Treat kernel type routes as EGP routes.
  123. * Changes in zebra-0.92
  124. ** Overall security is improved. Default umask is 0077.
  125. * Changes in ripd
  126. ** If output interface is in simple password authentication mode,
  127. substruct one from rtemax.
  128. * Changes in bgpd
  129. ** IPv4 multicast and IPv6 unicast configuration is changed to so
  130. called new config. All of AFI and SAFI specific configuration is
  131. moved to "address-family" node. When you have many IPv6 only
  132. configuration, you will see many "no neighbor X:X::X:X activate" line
  133. in your configuration to disable IPv4 unicast NLRI exchange. In that
  134. case please use "no bgp default ipv4-unicast" command to suppress the
  135. output. Until zebra-0.93, old config is still left for compatibility.

  223. ** SMUX can handle SNMP trap.
  224. ** In our event library, event thread is executed before any other
  225. thread like timer, read and write event.
  226. ** Robust method for writing configuration file and recover from
  227. backing up config file.
  228. ** Display "end" at the end of configuration.
  229. ** Fix memory leak in vtysh_read().
  230. ** Fix memroy leak about access-list and prefix-list name.
  231. * Changes in zebra
  232. ** UNIX domain socket server of zebra protocol is added.
  233. ** Fix PointoPoint interface network bug. The destination network
  234. should be installed into routing table instead of local network.
  235. ** Metric value is reflected to kernel routing table.
  236. ** "show ip route" display uptime of RIP,OSPF,BGP routes.
  237. ** New RIB implementation is added.
  238. Now we have enhanced RIB (routing information base) implementation in
  239. zebra. New RIB has many new features and fixed some bugs which exist
  240. in old RIB code.
  241. *** Static route with distance value
  242. Static route can be specified with administrative distance. The
  243. distance value 255 means it is not installed into the kernel.
  244. Default value of distance for static route is 1.
  245. ip route A.B.C.D/M A.B.C.D <1-255>
  246. ip route A.B.C.D/M IFNAME <1-255>
  247. If the least distance value's route's nexthop are unreachable,
  248. select the least distance value route which has reachable nexthop is
  249. selected.
  250. ip route 0.0.0.0/0 10.0.0.1
  251. ip route 0.0.0.0/0 11.0.0.1 2
  252. In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
  253. reachable. The route with nexthop 11.0.0.1 will be installed into
  254. forwarding table.
  255. zebra> show ip route
  256. S>* 0.0.0.0/0 [2/0] via 11.0.0.1
  257. S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
  258. If the nexthop is unreachable "inactive" is displayed. You can
  259. specify any string to IFNAME. There is no need of the interface is
  260. there when you configure the route.
  261. ip route 1.1.1.1/32 ppp0
  262. When ppp0 comes up, the route is installed properly.
  263. *** Multiple nexthop routes for one prefix
  264. Multiple nexthop routes can be specified for one prefix. Even the
  265. kernel support only one nexthop for one prefix user can configure
  266. multiple nexthop.
  267. When you configure routes like below, prefix 10.0.0.1 has three
  268. nexthop.
  269. ip route 10.0.0.1/32 10.0.0.2
  270. ip route 10.0.0.1/32 10.0.0.3
  271. ip route 10.0.0.1/32 eth0
  272. If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
  273. is reachable, then the last route is installed into the kernel.
  274. zebra> show ip route
  275. S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
  276. via 10.0.0.3 inactive
  277. * is directly connected, eth0
  278. '*' means this nexthop is installed into the kernel.
  279. *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
  280. When the kernel support multipath, zebra can install multipath
  281. routes into the kernel. Before doing that please make it sure that
  282. setting --enable-multipath=ARG to configure script. ARG must be digit
  283. value. When specify 0 to ARG, there is no limitation of the number
  284. of the multipath. Currently only GNU/Linux with netlink interface is
  285. supported.
  286. ip route 10.0.0.1/32 10.0.0.2
  287. ip route 10.0.0.1/32 10.0.0.3
  288. ip route 10.0.0.1/32 eth0
  289. zebra> show ip route
  290. S>* 10.0.0.1/32 [1/0] via 10.0.0.2
  291. * via 10.0.0.3
  292. is directly connected, eth0
  293. *** Kernel message delete installed route.
  294. After zebra install static or dynamic route into the kernel.
  295. R>* 0.0.0.0/0 [120/3] via 10.0.0.1
  296. If you delete this route outside zebra, old zebra does not reinstall
  297. route again. Now the route is re-processed and properly reinstall the
  298. static or dynamic route into the kernel.
  299. ** GNU/Linux netlink socket handling is improved to fix race condition
  300. between kernel message and user command responce.
  301. * Changes in bgpd
  302. ** Add show neighbor's routes command.
  303. "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
  304. "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
  305. "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
  306. "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
  307. ** BGP passive peer support problem is fixed.
  308. ** Redistributed IGP nexthop is passed to BGP nexthop.
  309. ** On multiaccess media, if the nexthop is reachable nexthop is passed
  310. as it is.
  311. ** Remove zebra-0.88 compatibility commands.
  312. "match ip prefix-list WORD"
  313. "match ipv6 prefix-list WORD"
  314. Instead of above please use below commands.
  315. "match ip address prefix-list WORD"
  316. "match ipv6 address prefix-list WORD"
  317. ** Fix bug of holdtimer is not reset when bgp cleared.

  322. has it's AS number in the first AS number in AS sequence.
  323. ** New route-map command "set community-delete COMMUNITY-LIST" is
  324. added. Community matched the CoMMUNITY-LIST is removed from the
  325. community.
  326. ** BGP-MIB implementation is finished.
  327. ** When BGP connection comes from unconfigured IP address, close
  328. socket immediately.
  329. ** Do not compare router ID when the routes comes from EBGP peer.
  330. When originator ID is same, take shorter cluster-list route. If
  331. cluster-list is same take smaller IP address neighbor's route.
  332. ** Add "bgp bestpath as-path ignore" command. When this option is
  333. set, do not concider AS path length when route selection.
  334. ** Add "bgp bestpath compare-routerid". When this option is set,
  335. compare router ID when the routes comes from EBGP peer.

  346. ** When a route is in garbage collection process (invalid with metric
  347. 16) and a router receives the same route with valid metric then route
  348. was not installed into zebra rib, but only into ripd rib. Moreover ,
  349. it will never get into zebra rib, because ripd wrongly assumes it's
  350. already there.
  351. * Change in ospfd
  352. ** Fix bug of refreshing default route.

  358. ** When there is no DR on network (suppose you have only one router
  359. with interface priority 0). It's router LSA does not contain the link
  360. information about this network.
  361. ** When you change a priority of interface from/to 0
  362. ISM_NeighborChange event should be scheduled in order to elect new
  363. DR/BDR on the network.
  364. ** When we add some LSA into retransmit list we need to check whether
  365. the present old LSA in retransmit list is not more recent than the new
  366. one.
  367. ** In states Loading and Full the slave must resend its last Database
  368. Description packet in response to duplicate Database Description
  369. packets received from the master. For this reason the slave must wait
  370. RouterDeadInterval seconds before freeing the last Database
  371. Description packet. Reception of a Database Description packet from
  372. the master after this interval will generate a SeqNumberMismatch
  373. neighbor event. RFC2328 Section 10.8

  629. ** It used to be "ip prefix-list A.B.C.D/M" match routes which mask >=
  630. M. Now default behavior is exact match so it only match routes which
  631. mask == M.
  632. * Changes in bgpd
  633. ** "match ip address prefix-list" is added to route-map.
  634. ** A route without local preference is evaluated as 100 local preference.
  635. ** Select smaller router-id route when other values are same.
  636. ** Compare MED only both routes comes from same neighboring AS.
  637. ** "bgp always-compare-med" command is added.
  638. ** Now MED value is passed to IBGP peer.
  639. ** When neighbor's filter is configured with non-existent access-list,
  640. as-path access-list, ip prefix-list, route-map. The behavior is
  641. changed from all permit to all deny.
  642. * Changes in ospfd
  643. ** Fix bug of external route tag byte order.

  654. changes.
  655. ** Increment LS age by configured interface transmit_delay.
  656. ** distribute-list is reimplemented.
  657. ** Fix bug of refresh never occurs.
  658. ** Fix bug of summary-LSAs reorigination. Correctly copy

  688. consume only one screen size memory.
  689. * Changes in ripd
  690. ** Fix debug output string.
  691. ** Add RIP peer handling. RIP peer are shown by "show ip protocols".
  692. * Changes in zebra-0.84a
  693. * Changes in bgpd
  694. ** Fix serious bug of BGP-4+ peering under IPv6 link-local address.
  695. Due to the bug BGP-4+ peering may not be established.
  696. * Changes in zebra-0.84
  697. * Changes in lib
  698. ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
  699. <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
  700. "X:X::X:X/M" for IPv6 prefix. You can use it like this.
  701. DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
  702. ** VTY configuration is locked during configuration. This is for
  703. avoiding unconditional crush from two terminals modify the
  704. configuration at the same time. "who" command shows which termnal
  705. lock the configuration. VTY which has '*' character at the head of
  706. line is locking the configuration.
  707. ** Old logging functions are removed. Functions like
  708. log_open,log_close,openlog are deleted. Instead of that please use
  709. zlog_* functions. zvlog_* used in ospf6d are deleted also.
  710. ** "terminal monitor" command is added. "no terminal monitor" is for
  711. disabling. This command simply display logging information to the
  712. VTY.
  713. ** dropline.[ch] files are deleted.
  714. * Changes in bgpd
  715. ** BGP neighbor configuration are sorted by it's IP address.
  716. ** BGP peer configuration and actual peer is separated. This is
  717. preparation for Route Server support.
  718. ** "no neighbor PEER" command is added. You can delete neighbor
  719. without specifying AS number.
  720. ** "no neighbor ebgp-multihop" command is added.
  721. ** "no neighbor port PORT" command is added.
  722. ** To conform RFC1771, "neighbor PEER send-community" is default
  723. behavior. If you want to disable sending community attribute,
  724. please specify "no neighbor PEER send-community" to the peer.
  725. ** "neighbor maximum-prefix NUMBER" command is added.
  726. ** Multi-protocol extention NLRI is proceeded only when the peer is
  727. configured proper Address Family and Subsequent Address Family. If
  728. not, those NLRI are simply ignored.
  729. ** Aggregate-address support is improved. Currently below commands
  730. works.
  731. "aggregate-address"
  732. "aggregate-address summary-only"
  733. "no aggregate-address"
  734. "no aggregate-address summary-only"
  735. "ipv6 bgp aggregate-address"
  736. "ipv6 bgp aggregate-address summary-only"
  737. "no ipv6 bgp aggregate-address"
  738. "no ipv6 bgp aggregate-address summary-only"
  739. ** redistribute route-map bug is fixed.
  740. ** MBGP support becomes default. "configure" option --enable-mbgp is
  741. removed.
  742. ** New command "neighbor PEER timers connect <1-65535>" is added.
  743. ** New command "neighbor PEER override-capability" is added.
  744. ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
  745. ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
  746. this command, you have to configure neighbor with
  747. "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
  748. * Changes in zebra-0.83
  749. * bgpd
  750. ** Serious bug fix about fetching global and link-local address at the
  751. same time. Due to this bug, corrupted IPv6 prefix is generated. If
  752. you uses bgpd for BGP-4+ please update to this version. The bug is
  753. introduced in zebra-0.82.
  754. ** When bgpd send Notify message, don't use thread manager. It is now
  755. send to neighbor immediately.
  756. * Changes in zebra-0.82
  757. ** Solaris 2.6 support is added by Michael Handler
  758. <handler@sub-rosa.com>.
  759. ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
  760. Please specify --enable-mbgp to configure script. This option will be
  761. removed in the future and MBGP support will be default.
  762. * Changes in zebra
  763. ** When interface goes down, withdraw connected routes from routing
  764. table. When interface goes up, restore the routes to the routing
  765. table.
  766. ** `show interface' show interface's statistics on Linux and BSD with
  767. routing socket.
  768. ** Now zebra can get MTU value on BSDI/OS.
  769. * Changes in bgpd
  770. ** Add capability option support based upon
  771. draft-ietf-idr-bgp4-cap-neg-04.txt.
  772. ** Add `show ipv6 bgp prefix-list' command.
  773. ** Check self AS appeared in received routes.
  774. ** redistribute route-map support is added.

  777. ** Fix bug of `timers basic' command's argument format.
  778. * Changes in ripngd
  779. ** Calculate max RTE using interface's MTU value.
  780. * Changes in ospfd
  781. ** Some correction to LSU processing.
  782. ** Add check for lsa->refresh_list.
  783. * Changes in ospf6d
  784. ** Many debug feature is added.
  785. * Changes in zebra-0.81
  786. ** SNMP support is disabled in default.--enable-snmp option is added
  787. to configure script.
  788. * Changes in bgpd
  789. ** Fix FSM bug which introduced in zebra-0.80.
  790. * Changes in zebra-0.80
  791. * access-list
  792. New access-list name space `ipv6 access-list' is added. At the same
  793. time, `access-list' statemant only accepts IPv4 prefix. Please be
  794. careful if you use IPv6 filtering. You will need to change your
  795. configuration. For IPv6 filtering please use `ipv6 access-list'.
  796. As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
  797. filtering.
  798. ! zebra-0.7x
  799. access-list DML-net permit 203.181.89.0/24
  800. access-list DML-net permit 3ffe:506::0/32
  801. access-list DML-net deny any
  802. !
  803. Above configuration is not valid for zebra-08x. Please add `ipv6'
  804. before 'access-list' when you configure IPv6 filtering.
  805. ! zebra-0.8x
  806. access-list DML-net permit 203.181.89.0/24
  807. access-list DML-net deny any
  808. !
  809. ipv6 access-list DML-net permit 3ffe:506::0/32
  810. ipv6 access-list DML-net deny any
  811. !
  812. * prefix-list
  813. And also new prefix-list name space `ipv6 prefix-list' is added. It
  814. is the same as the change of `access-list'. `ip prefix-list' now only
  815. accept IPv4 prefix. It was source of confusion that `ip prefix-list'
  816. can be used both IPv4 and IPv6 filtering. Now name space is separated
  817. to clear the meaning of the filter.
  818. If you use `ip prefix-list' for IPv6 filtering, please change the
  819. stetement.
  820. ! zebra-0.7x
  821. ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  822. ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  823. ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
  824. ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  825. ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  826. ip prefix-list 6bone-filter seq 30 deny any
  827. !
  828. Now user can explicitly configure it as IPv6 prefix-list.
  829. ! zebra-0.8x
  830. ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  831. ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  832. ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
  833. ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  834. ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  835. ipv6 prefix-list 6bone-filter seq 30 deny any
  836. !
  837. * RIP configuration
  838. If you want to filter only default route (0.0.0.0/0) and permit other
  839. routes, it was hard to do that. Now `ip prefix-list' can be used for
  840. RIP route filtering.
  841. New statement:
  842. `distribute-list prefix PLIST_NAME (in|out) IFNAME'
  843. is added to ripd. So you can configure on eth0 interface accept all
  844. routes other than default routes.
  845. !
  846. router rip
  847. distribute-list prefix filter-default in eth0
  848. !
  849. ip prefix-list filter-default deny 0.0.0.0/0 le 0
  850. ip prefix-list filter-default permit any
  851. !
  852. * RIPng configuration
  853. Same change is done for ripngd. You can use `ipv6 prefix-list' for
  854. filtering.
  855. !
  856. router ripng
  857. distribute-list prefix filter-default in eth0
  858. !
  859. ipv6 prefix-list filter-default deny ::/0 le 0
  860. ipv6 prefix-list filter-default permit any
  861. !
  862. * BGP configuration
  863. So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
  864. done with traditional IPv4 peering statement like blow.
  865. !
  866. router bgp 7675
  867. neighbor 3ffe:506::1 remote-as 2500
  868. neighbor 3ffe:506::1 prefix-list 6bone-filter out
  869. !
  870. For separating configuration IPv4 and IPv6, and for retaining Cisco
  871. configuration compatibility, now IPv6 configuration is done by IPv6
  872. specific statement. IPv6 BGP configuration is done by statement which
  873. start from `ipv6 bgp'.
  874. !
  875. router bgp 7675
  876. !
  877. ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
  878. ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
  879. !
  880. At the same time some IPv6 specific commands are deleted from IPv4
  881. configuration.
  882. o redistribute ripng
  883. o redistribute ospf6
  884. o neighbor PEER version BGP_VERSION
  885. o neighbor PEER interface IFNAME
  886. Those commands are only accepted as like below.
  887. o ipv6 bgp redistribute ripng
  888. o ipv6 bgp redistribute ospf6
  889. o ipv6 bgp neighbor PEER version BGP_VERSION
  890. o ipv6 bgp neighbor PEER interface IFNAME
  891. And below new commands are added.
  892. o ipv6 bgp network IPV6_PREFIX
  893. o ipv6 bgp redistribute static
  894. o ipv6 bgp redistribute connected
  895. o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
  896. o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
  897. o ipv6 bgp neighbor PEER description DESCRIPTION
  898. o ipv6 bgp neighbor PEER shutdown
  899. o ipv6 bgp neighbor PEER route-reflector-client
  900. o ipv6 bgp neighbor PEER update-source IFNAME
  901. o ipv6 bgp neighbor PEER next-hop-self
  902. o ipv6 bgp neighbor PEER timers holdtime <0-65535>
  903. o ipv6 bgp neighbor PEER timers keepalive <0-65535>
  904. o ipv6 bgp neighbor PEER send-community
  905. o ipv6 bgp neighbor PEER weight <0-65535>
  906. o ipv6 bgp neighbor PEER default-originate
  907. o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
  908. o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
  909. o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
  910. o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
  911. And some utility commands are introduced.
  912. o clear ipv6 bgp [PEER]
  913. o show ipv6 bgp neighbors [PEER]
  914. o show ipv6 bgp summary
  915. I hope these changes are easy to understand for current Zebra users...
  916. * To restrict connection to VTY interface.
  917. It used to be both IPv4 and IPv6 filter can be specified with one
  918. access-list. Then the access-list can be appried to VTY interface
  919. with `access-class' stetement in `line vty' node. Below is example in
  920. zebra-0.7x.
  921. !
  922. access-list local-only permit 127.0.0.1/32
  923. access-list local-only permit ::1/128
  924. access-list local-only deny any
  925. !
  926. line vty
  927. access-class local-only
  928. !
  929. Now IPv4 and IPv6 filter have each name space. It is not possible to
  930. specify IPv4 and IPv6 filter with one access-list. For setting IPv6
  931. access-list in `line vty', `ipv6 access-class' statement is
  932. introduced. Let me show the configuration in zebra-0.8x.
  933. !
  934. access-list local-only permit 127.0.0.1/32
  935. access-list local-only deny any
  936. !
  937. ipv6 access-list local-only permit ::1/128
  938. ipv6 access-list local-only dny any
  939. !
  940. line vty
  941. access-class local-only
  942. ipv6 access-class local-only
  943. !
  944. * route-map
  945. New IPv6 related route-map match commands are added.
  946. o match ipv6 address
  947. o match ipv6 next-hop
  948. Please change your configuration if you use IP match statement for
  949. IPv6 route.
  950. zebra-0.7x config
  951. =================
  952. !
  953. access-list all permit any
  954. !
  955. route-map set-nexthop permit 10
  956. match ip address all
  957. set ipv6 next-hop global 3ffe:506::1
  958. set ipv6 next-hop local fe80::cbb5:591a
  959. !
  960. zebra-0.8x config
  961. =================
  962. !
  963. ipv6 access-list all permit any
  964. !
  965. route-map set-nexthop permit 10
  966. match ipv6 address all
  967. set ipv6 next-hop global 3ffe:506::1
  968. set ipv6 next-hop local fe80::cbb5:591a
  969. !
  970. * zebra connection
  971. Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
  972. when the connection fail. Those daemons try to connect zebra every 10
  973. seconds first three trial, then the interval changed to 60 seconds.
  974. After all, if ten connections are fail, protocol daemon give up the
  975. connection to the zebra daemon.
  976. * SNMP support (is not yet finished)
  977. Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
  978. agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
  979. and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
  980. compiled with ucd-snmp-3.6.2.
  981. After applying the patch to ucd-snmp-4.0.1, please configure it with
  982. SMUX module.
  983. % configure --with-mib-modules=smux
  984. After compile & install ucd-snmp-4.0.1, you will need to configure
  985. smuxpeer. I'm now using below configuration.
  986. /usr/local/share/snmp/snmpd.conf
  987. ================================
  988. smuxpeer 1.3.6.1.6.3.1 test
  989. Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
  990. coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
  991. * HUP signal treatment
  992. From zebra-0.80, ripd will reload it's configuration file when ripd
  993. receives HUP signal. Other daemon such as bgpd, ospfd will support
  994. HUP signal treatment soon.
  995. * Changes in zebra-0.79
  996. * Changes in zebra
  997. ** Broadcast address setting on Linux box bug is fixed.
  998. ** Protocol daemon can install connected IPv6 route into the kernel.

  1003. netmask pair which host part bit is on, ignore the entry.
  1004. * Changes in ripngd
  1005. ** Change CMSG_DATA cast from (u_char *) to (int *). (u_char *) does
  1006. not work for NetBSD-currnet on SparcStation 10.

  1019. * Changes in zebra
  1020. ** Interface index detection using ioctl() bug is fixed.
  1021. ** Interface information protocol is changed. Now interface
  1022. addition/deletion and interface's address addition/deletion is
  1023. separated.
  1024. * Changes in bgpd
  1025. ** BGP hold timer bug is fixed.
  1026. ** BGP keepavlie timer becomes configurable.
  1027. * Changes in ripd
  1028. ** When making reply to rip's REQUEST message, fill in
  1029. RIP_METRIC_INFINITY with network byte order using htonl ().
  1030. ** Pass host byte order address to IN_CLASSC and IN_CLASSB macro.
  1031. * Changes in ospfd
  1032. ** LSA flooding works.
  1033. ** Fix bug of DD processing.
  1034. ** Fix bug of originating router-LSA bug is fixed.
  1035. ** LSA structure is changed to support LSA aging.
  1036. * Changes in ospf6d
