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

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

  226. ** Fix PointoPoint interface network bug. The destination network
  227. should be installed into routing table instead of local network.
  228. ** Metric value is reflected to kernel routing table.
  229. ** "show ip route" display uptime of RIP,OSPF,BGP routes.
  230. ** New RIB implementation is added.
  231. Now we have enhanced RIB (routing information base) implementation in
  232. zebra. New RIB has many new features and fixed some bugs which exist
  233. in old RIB code.
  234. *** Static route with distance value
  235. Static route can be specified with administrative distance. The
  236. distance value 255 means it is not installed into the kernel.
  237. Default value of distance for static route is 1.
  238. ip route A.B.C.D/M A.B.C.D <1-255>
  239. ip route A.B.C.D/M IFNAME <1-255>
  240. If the least distance value's route's nexthop are unreachable,
  241. select the least distance value route which has reachable nexthop is
  242. selected.
  243. ip route 0.0.0.0/0 10.0.0.1
  244. ip route 0.0.0.0/0 11.0.0.1 2
  245. In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
  246. reachable. The route with nexthop 11.0.0.1 will be installed into
  247. forwarding table.
  248. zebra> show ip route
  249. S>* 0.0.0.0/0 [2/0] via 11.0.0.1
  250. S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
  251. If the nexthop is unreachable "inactive" is displayed. You can
  252. specify any string to IFNAME. There is no need of the interface is
  253. there when you configure the route.
  254. ip route 1.1.1.1/32 ppp0
  255. When ppp0 comes up, the route is installed properly.
  256. *** Multiple nexthop routes for one prefix
  257. Multiple nexthop routes can be specified for one prefix. Even the
  258. kernel support only one nexthop for one prefix user can configure
  259. multiple nexthop.
  260. When you configure routes like below, prefix 10.0.0.1 has three
  261. nexthop.
  262. ip route 10.0.0.1/32 10.0.0.2
  263. ip route 10.0.0.1/32 10.0.0.3
  264. ip route 10.0.0.1/32 eth0
  265. If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
  266. is reachable, then the last route is installed into the kernel.
  267. zebra> show ip route
  268. S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
  269. via 10.0.0.3 inactive
  270. * is directly connected, eth0
  271. '*' means this nexthop is installed into the kernel.
  272. *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
  273. When the kernel support multipath, zebra can install multipath
  274. routes into the kernel. Before doing that please make it sure that
  275. setting --enable-multipath=ARG to configure script. ARG must be digit
  276. value. When specify 0 to ARG, there is no limitation of the number
  277. of the multipath. Currently only GNU/Linux with netlink interface is
  278. supported.
  279. ip route 10.0.0.1/32 10.0.0.2
  280. ip route 10.0.0.1/32 10.0.0.3
  281. ip route 10.0.0.1/32 eth0
  282. zebra> show ip route
  283. S>* 10.0.0.1/32 [1/0] via 10.0.0.2
  284. * via 10.0.0.3
  285. is directly connected, eth0
  286. *** Kernel message delete installed route.
  287. After zebra install static or dynamic route into the kernel.
  288. R>* 0.0.0.0/0 [120/3] via 10.0.0.1
  289. If you delete this route outside zebra, old zebra does not reinstall
  290. route again. Now the route is re-processed and properly reinstall the
  291. static or dynamic route into the kernel.
  292. ** GNU/Linux netlink socket handling is improved to fix race condition
  293. between kernel message and user command responce.
  294. * Changes in bgpd
  295. ** Add show neighbor's routes command.
  296. "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
  297. "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
  298. "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
  299. "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
  300. ** BGP passive peer support problem is fixed.
  301. ** Redistributed IGP nexthop is passed to BGP nexthop.
  302. ** On multiaccess media, if the nexthop is reachable nexthop is passed
  303. as it is.
  304. ** Remove zebra-0.88 compatibility commands.
  305. "match ip prefix-list WORD"
  306. "match ipv6 prefix-list WORD"
  307. Instead of above please use below commands.
  308. "match ip address prefix-list WORD"
  309. "match ipv6 address prefix-list WORD"
  310. ** Fix bug of holdtimer is not reset when bgp cleared.
  311. ** "show ip bgp summary" display peer establish/drop count.
  312. ** Change "match ip next-hop" argument from IP address to access-list
  313. name.
  314. ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
  315. has it's AS number in the first AS number in AS sequence.
  316. ** New route-map command "set community-delete COMMUNITY-LIST" is
  317. added. Community matched the CoMMUNITY-LIST is removed from the
  318. community.
  319. ** BGP-MIB implementation is finished.
  320. ** When BGP connection comes from unconfigured IP address, close
  321. socket immediately.
  322. ** Do not compare router ID when the routes comes from EBGP peer.
  323. When originator ID is same, take shorter cluster-list route. If
  324. cluster-list is same take smaller IP address neighbor's route.
  325. ** Add "bgp bestpath as-path ignore" command. When this option is
  326. set, do not concider AS path length when route selection.
  327. ** Add "bgp bestpath compare-routerid". When this option is set,
  328. compare router ID when the routes comes from EBGP peer.
  329. ** Add "bgp deterministic-med" process.
  330. ** BGP flap dampening feature is added.
  331. ** When IBGP nexthop is changed, it is reflected to RIB.

  336. name.
  337. ** "no ip rip (send|receive)" command accept version number argument.
  338. ** Memory leak related classfull network generation is fixed.
  339. ** When a route is in garbage collection process (invalid with metric
  340. 16) and a router receives the same route with valid metric then route
  341. was not installed into zebra rib, but only into ripd rib. Moreover ,
  342. it will never get into zebra rib, because ripd wrongly assumes it's
  343. already there.
  344. * Change in ospfd
  345. ** Fix bug of refreshing default route.
  346. ** --enable-nssa turn on undergoing NSSA feature.

  348. comes up.
  349. ** Reduce unconditional logging.
  350. ** Add nexthop to OSPF path only when it is not there.
  351. ** When there is no DR on network (suppose you have only one router
  352. with interface priority 0). It's router LSA does not contain the link
  353. information about this network.
  354. ** When you change a priority of interface from/to 0
  355. ISM_NeighborChange event should be scheduled in order to elect new
  356. DR/BDR on the network.
  357. ** When we add some LSA into retransmit list we need to check whether
  358. the present old LSA in retransmit list is not more recent than the new
  359. one.
  360. ** In states Loading and Full the slave must resend its last Database
  361. Description packet in response to duplicate Database Description
  362. packets received from the master. For this reason the slave must wait
  363. RouterDeadInterval seconds before freeing the last Database
  364. Description packet. Reception of a Database Description packet from
  365. the master after this interval will generate a SeqNumberMismatch
  366. neighbor event. RFC2328 Section 10.8
  367. ** Virtual link can not configured in stub area.
  368. ** Clear a ls_upd_queue queue of the interface when interface goes

  399. ** route-map and access-list configuration is merged into one
  400. configuration.
  401. ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
  402. memory" in vtysh will write whole configuration to this file.
  403. ** When -b option is specified to vtysh, vtysh read
  404. /usr/local/etc/Zebra.conf file then pass the confuguration to proper

  681. consume only one screen size memory.
  682. * Changes in ripd
  683. ** Fix debug output string.
  684. ** Add RIP peer handling. RIP peer are shown by "show ip protocols".
  685. * Changes in zebra-0.84a
  686. * Changes in bgpd
  687. ** Fix serious bug of BGP-4+ peering under IPv6 link-local address.
  688. Due to the bug BGP-4+ peering may not be established.
  689. * Changes in zebra-0.84
  690. * Changes in lib
  691. ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
  692. <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
  693. "X:X::X:X/M" for IPv6 prefix. You can use it like this.
  694. DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
  695. ** VTY configuration is locked during configuration. This is for
  696. avoiding unconditional crush from two terminals modify the
  697. configuration at the same time. "who" command shows which termnal
  698. lock the configuration. VTY which has '*' character at the head of
  699. line is locking the configuration.
  700. ** Old logging functions are removed. Functions like
  701. log_open,log_close,openlog are deleted. Instead of that please use
  702. zlog_* functions. zvlog_* used in ospf6d are deleted also.
  703. ** "terminal monitor" command is added. "no terminal monitor" is for
  704. disabling. This command simply display logging information to the
  705. VTY.
  706. ** dropline.[ch] files are deleted.
  707. * Changes in bgpd
  708. ** BGP neighbor configuration are sorted by it's IP address.
  709. ** BGP peer configuration and actual peer is separated. This is
  710. preparation for Route Server support.
  711. ** "no neighbor PEER" command is added. You can delete neighbor
  712. without specifying AS number.
  713. ** "no neighbor ebgp-multihop" command is added.
  714. ** "no neighbor port PORT" command is added.
  715. ** To conform RFC1771, "neighbor PEER send-community" is default

  717. please specify "no neighbor PEER send-community" to the peer.
  718. ** "neighbor maximum-prefix NUMBER" command is added.
  719. ** Multi-protocol extention NLRI is proceeded only when the peer is
  720. configured proper Address Family and Subsequent Address Family. If
  721. not, those NLRI are simply ignored.
  722. ** Aggregate-address support is improved. Currently below commands
  723. works.
  724. "aggregate-address"
  725. "aggregate-address summary-only"
  726. "no aggregate-address"
  727. "no aggregate-address summary-only"
  728. "ipv6 bgp aggregate-address"

  732. ** redistribute route-map bug is fixed.
  733. ** MBGP support becomes default. "configure" option --enable-mbgp is
  734. removed.
  735. ** New command "neighbor PEER timers connect <1-65535>" is added.
  736. ** New command "neighbor PEER override-capability" is added.
  737. ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
  738. ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
  739. this command, you have to configure neighbor with
  740. "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
  741. * Changes in zebra-0.83
  742. * bgpd
  743. ** Serious bug fix about fetching global and link-local address at the
  744. same time. Due to this bug, corrupted IPv6 prefix is generated. If
  745. you uses bgpd for BGP-4+ please update to this version. The bug is
  746. introduced in zebra-0.82.
  747. ** When bgpd send Notify message, don't use thread manager. It is now
  748. send to neighbor immediately.
  749. * Changes in zebra-0.82
  750. ** Solaris 2.6 support is added by Michael Handler
  751. <handler@sub-rosa.com>.
  752. ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
  753. Please specify --enable-mbgp to configure script. This option will be
  754. removed in the future and MBGP support will be default.
  755. * Changes in zebra
  756. ** When interface goes down, withdraw connected routes from routing
  757. table. When interface goes up, restore the routes to the routing
  758. table.
  759. ** `show interface' show interface's statistics on Linux and BSD with
  760. routing socket.
  761. ** Now zebra can get MTU value on BSDI/OS.
  762. * Changes in bgpd

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