  1. Note: this file lists major user-visible changes only.
  2. * Changes in Quagga 0.99.23
  3. Known issues:
  4. - [bgpd] setting an extcommunity in a route map on a route that already has
  5. an extcommunity attribute will cause bgpd to crash. This issue will be
  6. fixed in a followup minor release.
  7. User-visible changes:
  8. - [lib] Performance enhancements on hashes and timers.
  9. - [bgpd] New feature: iBGP TTL security.
  10. - [bgpd] New feature: relaxed bestpath criteria for multipath and improved
  11. display of multipath routes in "show ip bgp". Scripts parsing this output
  12. may need to be updated.
  13. - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate
  14. IPv4 nexthop by looking at the interface.
  15. - [ospf6d] A large amount of changes has been merged for ospf6d. Careful
  16. evaluation prior to deployment is recommended.
  17. - [zebra] Recursive route support has been overhauled. Scripts parsing
  18. "show ip route" output may need adaptation.
  19. - [zebra] IPv6 address management has been improved regarding tentative
  20. addresses. This is visible in that a freshly configured address will not
  21. immediately be marked as usable.
  22. - [*] a lot of bugs have been fixed, please refer to the git log
  23. * Changes in Quagga 0.99.22
  24. - [bgpd] The semantics of default-originate route-map have changed.
  25. The route-map is now used to advertise the default route conditionally.
  26. The old behaviour which allowed to set attributes on the originated
  27. default route is no longer supported.
  28. - [bgpd] There is now a replace-as option to neighbor ... local-as ...
  29. no-prepend. For details, refer to the user documentation.
  30. - [zebra] An FPM interface has been added. This provides an alternate
  31. interface to routing information and is geared at OpenFlow & co.
  32. - [snmp] AgentX is now supported; the old smux backend is considered
  33. deprecated. ospf6d has also had OSPFV3-MIB added.
  34. - [*] several issues with configuration save/load/apply have been fixed,
  35. in particular on ospf "max-metric router-lsa administrative" and
  36. "distribute-list", bgpd "no neighbor activate", isisd "metric-style",
  37. - [*] a lot of bugs have been fixed, please refer to the git log
  38. * Changes in Quagga 0.99.21
  39. - [bgpd] BGP multipath support has been merged
  40. - [bgpd] SAFI (Multicast topology) support has been extended to propagate
  41. the topology to zebra.
  42. - [bgpd] AS path limit functionality has been removed
  43. - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
  44. protocol has been merged.
  45. - [isisd] a major overhaul has been picked up. Please note that isisd is
  46. STILL NOT SUITABLE FOR PRODUCTION USE.
  47. - [*] a lot of bugs have been fixed, please refer to the git log
  48. * Changes in Quagga 0.99.10
  49. - [bgpd] 4-byte AS support added
  50. - [bgpd] MRT format changes to version 2. Those relying on
  51. bgpd MRT table dumps may need to update their tools.
  52. - [bgpd] Added new route-map set statement: "as-path exclude"
  53. - Zebra RIB updates queue has evolved into a multi-level
  54. structure to address RIB consistency issues.
  55. * Changes in Quagga 0.99.2
  56. - [bgpd] Work queues added to bgpd to split up update processing,
  57. particularly beneficial when a peer session goes down. AS_PATH
  58. parsing rewritten to be clearer, more robust and ready for 4-byte.
  59. - [ripd] Simple authentication is no longer the default authentication
  60. mode for ripd. The default is now no-authentication. Any setups which
  61. used simple authentication will probably need to update their
  62. configuration manually.
  63. - [ospfd] 1s dead-interval with sub-second Hellos feature added.
  64. SPF timers now specified in milliseconds, and with adaptive
  65. hold-time support. RFC3137 Stub-router support added. Default ABR
  66. type is now 'cisco'.
  67. - Solaris least privileges support added.
  68. * Changes in Quagga 0.99.1
  69. - Zserv is now buffered via threads and non-blocking in most cases for both
  70. clients and zebra, which should improve responsiveness of daemons when
  71. they must send many messages to zebra.
  72. - 'show thread cpu' now displays both cpu+system and wall-clock time,
  73. where getrusage() is available.
  74. - Background threads added and workqueue API added, with a
  75. 'show work-queues' command. Thread scheduling improved slightly.
  76. - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
  77. the zebra daemon vty.
  78. - Support for interface renaming on Linux netlink systems.
  79. - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
  80. route-source" command.
  81. - Automatic logging of backtraces should daemons crash to assist in
  82. diagnosis. See the documentation for more information on configuring
  83. logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
  84. * Changes in Quagga 0.98.0
  85. - Logging facilities upgraded. One can now specify a severity level
  86. for each logging destination. And a new "show logging" command gives
  87. thorough information on the current logging system configuration.
  88. - Watchquagga daemon added. This is not well tested yet. Please try
  89. monitor mode first before enabling restart features. It is important
  90. to make sure that the various timers are configured with appropriate
  91. values for your site.
  92. - BGP route-server support added. See the texinfo documentation.
  93. - OSPF API initialisation is disabled by default even if compiled in. You
  94. can enable it with -a/--apiserver command line switch.
  95. - "write-config integrated" vtysh command replaced with "service
  96. integrated-vtysh-config" command.
  97. - Router id is now handled by zebra daemon and all daemons receive changes
  98. from it. Router id can be overriden in daemons' configurations of course.
  99. To fix common router id in zebra daemon you can either install non-127
  100. address on loopback or use "router-id x.x.x.x" command.
  101. - "secondary" keyword is removed from ip address configuration. All
  102. supported OS'es have their own vision what's secondary address and
  103. how to handle it.
  104. - Zebra no longer enables forwarding by default. If you rely on zebra to
  105. enable forwarding make sure to add '<ip|ip6> forwarding' statements
  106. to your zebra configuration file.
  107. - All libraries are built and used shared, on platforms where libtool
  108. supports shared libraries.
  109. - Router advertisement syntax is changed. In usual cases (if you didn't do
  110. any fancy stuff) it's enough to change lines in configuration from:
  111. "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
  112. to:
  113. "ipv6 nd prefix X:X:X:X::/X"
  114. All router advertisement options are documented in texi documentation.
  115. - --enable-nssa configure switch is removed. NSSA support is stable enough.
  116. - Daemons don't look at current directory for config file any more.
  117. * Changes in Quagga 0.96.5
  118. - include files are installed in $(prefix)/include/quagga. Programs
  119. building against these includes should -I$(prefix)/include and e.g.
  120. #include <quagga/routemap.h>
  121. - New option --enable-exampledir puts example files in a separate
  122. directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
  123. compliance.
  124. - New configure options --enable-configfile-mask and
  125. --enable-logfile-mask to set umask values for config and log
  126. values. Masks default to 0600, matching previous behavior.
  127. - Import current CVS isisd from SourceForge, then merge it with
  128. the Quagga's Framework.
  129. * Changes in Quagga 0.96.4
  130. - Further fixes to ospfd, some relating to the PtP revert. Interface
  131. lookups should be a lot more robust now.
  132. - Fix for a remote triggerable crash in vty layer.
  133. - Improvements to ripd, and addition of split horizon support.
  134. - Improved bgpd table support, now dumps at time of day intervals rather
  135. than time from startup intervals. Much improved support for IPv6 table
  136. dumps. show commands for views improved.
  137. * Changes in Quagga 0.96.3
  138. - revert the 'generic PtP' patch. Means Quagga will no longer work with
  139. FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
  140. which the PtP patch introduced.
  141. * Changes in Quagga 0.96.2
  142. - Fix crash in ospfd
  143. * Changes in Quagga 0.96.1
  144. - Iron out problem with the privileges definitions
  145. * Changes in Quagga 0.96
  146. - Privilege support, daemons now run with the minimal privileges needed, see
  147. the documentation for details.
  148. - NSSA ABR support in ospfd.
  149. - OSPF-API support merged in.
  150. - 6WIND patch merged in.
  151. * Changes in zebra-0.93
  152. * Changes in bgpd
  153. ** Configuration is changed to new format.
  154. * Changes in ospfd
  155. ** Crush bugs which reported on Zebra ML is fixed.
  156. ** Opaque LSA and TE LSA support is added by KDD R&D Laboratories,
  157. Inc.
  158. * Chages in ospf6d
  159. ** Many bugs are fixed.
  160. * Changes in zebra-0.92a
  161. * Changes in bgpd
  162. ** Fix "^$" community list bug.
  163. ** Below command's Address Family specific configurations are added
  164. nexthop-self
  165. route-reflector-client
  166. route-server-client
  167. soft-reconfiguration inbound
  168. * Changes in zebra
  169. ** Treat kernel type routes as EGP routes.
  170. * Changes in zebra-0.92
  171. ** Overall security is improved. Default umask is 0077.
  172. * Changes in ripd
  173. ** If output interface is in simple password authentication mode,
  174. substruct one from rtemax.
  175. * Changes in bgpd
  176. ** IPv4 multicast and IPv6 unicast configuration is changed to so
  177. called new config. All of AFI and SAFI specific configuration is
  178. moved to "address-family" node. When you have many IPv6 only
  179. configuration, you will see many "no neighbor X:X::X:X activate" line
  180. in your configuration to disable IPv4 unicast NLRI exchange. In that
  181. case please use "no bgp default ipv4-unicast" command to suppress the
  182. output. Until zebra-0.93, old config is still left for compatibility.

  284. ** New RIB implementation is added.
  285. Now we have enhanced RIB (routing information base) implementation in
  286. zebra. New RIB has many new features and fixed some bugs which exist
  287. in old RIB code.
  288. *** Static route with distance value
  289. Static route can be specified with administrative distance. The
  290. distance value 255 means it is not installed into the kernel.
  291. Default value of distance for static route is 1.
  292. ip route A.B.C.D/M A.B.C.D <1-255>
  293. ip route A.B.C.D/M IFNAME <1-255>
  294. If the least distance value's route's nexthop are unreachable,
  295. select the least distance value route which has reachable nexthop is
  296. selected.
  297. ip route 0.0.0.0/0 10.0.0.1
  298. ip route 0.0.0.0/0 11.0.0.1 2
  299. In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
  300. reachable. The route with nexthop 11.0.0.1 will be installed into
  301. forwarding table.
  302. zebra> show ip route
  303. S>* 0.0.0.0/0 [2/0] via 11.0.0.1
  304. S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
  305. If the nexthop is unreachable "inactive" is displayed. You can
  306. specify any string to IFNAME. There is no need of the interface is
  307. there when you configure the route.
  308. ip route 1.1.1.1/32 ppp0
  309. When ppp0 comes up, the route is installed properly.
  310. *** Multiple nexthop routes for one prefix
  311. Multiple nexthop routes can be specified for one prefix. Even the
  312. kernel support only one nexthop for one prefix user can configure
  313. multiple nexthop.
  314. When you configure routes like below, prefix 10.0.0.1 has three
  315. nexthop.
  316. ip route 10.0.0.1/32 10.0.0.2
  317. ip route 10.0.0.1/32 10.0.0.3
  318. ip route 10.0.0.1/32 eth0
  319. If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
  320. is reachable, then the last route is installed into the kernel.
  321. zebra> show ip route
  322. S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
  323. via 10.0.0.3 inactive
  324. * is directly connected, eth0
  325. '*' means this nexthop is installed into the kernel.
  326. *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
  327. When the kernel support multipath, zebra can install multipath
  328. routes into the kernel. Before doing that please make it sure that
  329. setting --enable-multipath=ARG to configure script. ARG must be digit
  330. value. When specify 0 to ARG, there is no limitation of the number
  331. of the multipath. Currently only GNU/Linux with netlink interface is
  332. supported.
  333. ip route 10.0.0.1/32 10.0.0.2
  334. ip route 10.0.0.1/32 10.0.0.3
  335. ip route 10.0.0.1/32 eth0
  336. zebra> show ip route
  337. S>* 10.0.0.1/32 [1/0] via 10.0.0.2
  338. * via 10.0.0.3
  339. is directly connected, eth0
  340. *** Kernel message delete installed route.
  341. After zebra install static or dynamic route into the kernel.
  342. R>* 0.0.0.0/0 [120/3] via 10.0.0.1
  343. If you delete this route outside zebra, old zebra does not reinstall
  344. route again. Now the route is re-processed and properly reinstall the
  345. static or dynamic route into the kernel.
  346. ** GNU/Linux netlink socket handling is improved to fix race condition
  347. between kernel message and user command responce.
  348. * Changes in bgpd
  349. ** Add show neighbor's routes command.
  350. "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
  351. "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
  352. "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
  353. "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
  354. ** BGP passive peer support problem is fixed.
  355. ** Redistributed IGP nexthop is passed to BGP nexthop.
  356. ** On multiaccess media, if the nexthop is reachable nexthop is passed
  357. as it is.
  358. ** Remove zebra-0.88 compatibility commands.
  359. "match ip prefix-list WORD"
  360. "match ipv6 prefix-list WORD"
  361. Instead of above please use below commands.
  362. "match ip address prefix-list WORD"
  363. "match ipv6 address prefix-list WORD"
  364. ** Fix bug of holdtimer is not reset when bgp cleared.
  365. ** "show ip bgp summary" display peer establish/drop count.

  371. added. Community matched the CoMMUNITY-LIST is removed from the
  372. community.
  373. ** BGP-MIB implementation is finished.
  374. ** When BGP connection comes from unconfigured IP address, close
  375. socket immediately.
  376. ** Do not compare router ID when the routes comes from EBGP peer.
  377. When originator ID is same, take shorter cluster-list route. If
  378. cluster-list is same take smaller IP address neighbor's route.
  379. ** Add "bgp bestpath as-path ignore" command. When this option is
  380. set, do not concider AS path length when route selection.

  393. ** When a route is in garbage collection process (invalid with metric
  394. 16) and a router receives the same route with valid metric then route
  395. was not installed into zebra rib, but only into ripd rib. Moreover ,
  396. it will never get into zebra rib, because ripd wrongly assumes it's
  397. already there.
  398. * Change in ospfd
  399. ** Fix bug of refreshing default route.
  400. ** --enable-nssa turn on undergoing NSSA feature.

  405. ** When there is no DR on network (suppose you have only one router
  406. with interface priority 0). It's router LSA does not contain the link
  407. information about this network.
  408. ** When you change a priority of interface from/to 0
  409. ISM_NeighborChange event should be scheduled in order to elect new
  410. DR/BDR on the network.
  411. ** When we add some LSA into retransmit list we need to check whether
  412. the present old LSA in retransmit list is not more recent than the new
  413. one.
  414. ** In states Loading and Full the slave must resend its last Database
  415. Description packet in response to duplicate Database Description
  416. packets received from the master. For this reason the slave must wait
  417. RouterDeadInterval seconds before freeing the last Database
  418. Description packet. Reception of a Database Description packet from
  419. the master after this interval will generate a SeqNumberMismatch
  420. neighbor event. RFC2328 Section 10.8

  453. ** route-map and access-list configuration is merged into one
  454. configuration.
  455. ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
  456. memory" in vtysh will write whole configuration to this file.
  457. ** When -b option is specified to vtysh, vtysh read
  458. /usr/local/etc/Zebra.conf file then pass the confuguration to proper
  459. protocol daemon. So make all protocol daemon's configuration file

  745. ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
  746. <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
  747. "X:X::X:X/M" for IPv6 prefix. You can use it like this.
  748. DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
  749. ** VTY configuration is locked during configuration. This is for
  750. avoiding unconditional crush from two terminals modify the
  751. configuration at the same time. "who" command shows which termnal
  752. lock the configuration. VTY which has '*' character at the head of
  753. line is locking the configuration.
  754. ** Old logging functions are removed. Functions like
  755. log_open,log_close,openlog are deleted. Instead of that please use
  756. zlog_* functions. zvlog_* used in ospf6d are deleted also.
  757. ** "terminal monitor" command is added. "no terminal monitor" is for
  758. disabling. This command simply display logging information to the
  759. VTY.
  760. ** dropline.[ch] files are deleted.
  761. * Changes in bgpd
  762. ** BGP neighbor configuration are sorted by it's IP address.
  763. ** BGP peer configuration and actual peer is separated. This is
  764. preparation for Route Server support.

  771. please specify "no neighbor PEER send-community" to the peer.
  772. ** "neighbor maximum-prefix NUMBER" command is added.
  773. ** Multi-protocol extention NLRI is proceeded only when the peer is
  774. configured proper Address Family and Subsequent Address Family. If
  775. not, those NLRI are simply ignored.

  786. ** redistribute route-map bug is fixed.
  787. ** MBGP support becomes default. "configure" option --enable-mbgp is
  788. removed.
  789. ** New command "neighbor PEER timers connect <1-65535>" is added.
  790. ** New command "neighbor PEER override-capability" is added.
  791. ** New command "show ip bgp neighbor A.B.C.D advertised-route" is added.
  792. ** New command "show ip bgp neighbor A.B.C.D routes" is added. To use
  793. this command, you have to configure neighbor with
  794. "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
  795. * Changes in zebra-0.83
  796. * bgpd
  797. ** Serious bug fix about fetching global and link-local address at the
  798. same time. Due to this bug, corrupted IPv6 prefix is generated. If
  799. you uses bgpd for BGP-4+ please update to this version. The bug is
  800. introduced in zebra-0.82.
  801. ** When bgpd send Notify message, don't use thread manager. It is now
  802. send to neighbor immediately.
  803. * Changes in zebra-0.82
  804. ** Solaris 2.6 support is added by Michael Handler
  805. <handler@sub-rosa.com>.
  806. ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
  807. Please specify --enable-mbgp to configure script. This option will be
  808. removed in the future and MBGP support will be default.
  809. * Changes in zebra
  810. ** When interface goes down, withdraw connected routes from routing
  811. table. When interface goes up, restore the routes to the routing
  812. table.
  813. ** `show interface' show interface's statistics on Linux and BSD with
  814. routing socket.
  815. ** Now zebra can get MTU value on BSDI/OS.
  816. * Changes in bgpd
  817. ** Add capability option support based upon
  818. draft-ietf-idr-bgp4-cap-neg-04.txt.
  819. ** Add `show ipv6 bgp prefix-list' command.
  820. ** Check self AS appeared in received routes.

  825. * Changes in ripngd
  826. ** Calculate max RTE using interface's MTU value.
  827. * Changes in ospfd
  828. ** Some correction to LSU processing.
  829. ** Add check for lsa->refresh_list.
  830. * Changes in ospf6d
  831. ** Many debug feature is added.
  832. * Changes in zebra-0.81
  833. ** SNMP support is disabled in default.--enable-snmp option is added
  834. to configure script.
  835. * Changes in bgpd
  836. ** Fix FSM bug which introduced in zebra-0.80.
  837. * Changes in zebra-0.80
  838. * access-list
  839. New access-list name space `ipv6 access-list' is added. At the same
  840. time, `access-list' statemant only accepts IPv4 prefix. Please be
  841. careful if you use IPv6 filtering. You will need to change your
  842. configuration. For IPv6 filtering please use `ipv6 access-list'.
  843. As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
  844. filtering.
  845. ! zebra-0.7x
  846. access-list DML-net permit 203.181.89.0/24
  847. access-list DML-net permit 3ffe:506::0/32
  848. access-list DML-net deny any
  849. !
  850. Above configuration is not valid for zebra-08x. Please add `ipv6'
  851. before 'access-list' when you configure IPv6 filtering.
  852. ! zebra-0.8x
  853. access-list DML-net permit 203.181.89.0/24
  854. access-list DML-net deny any
  855. !
  856. ipv6 access-list DML-net permit 3ffe:506::0/32
  857. ipv6 access-list DML-net deny any
  858. !
  859. * prefix-list
  860. And also new prefix-list name space `ipv6 prefix-list' is added. It
  861. is the same as the change of `access-list'. `ip prefix-list' now only
  862. accept IPv4 prefix. It was source of confusion that `ip prefix-list'
  863. can be used both IPv4 and IPv6 filtering. Now name space is separated
  864. to clear the meaning of the filter.
  865. If you use `ip prefix-list' for IPv6 filtering, please change the
  866. stetement.
  867. ! zebra-0.7x
  868. ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  869. ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  870. ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
  871. ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  872. ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  873. ip prefix-list 6bone-filter seq 30 deny any
  874. !
  875. Now user can explicitly configure it as IPv6 prefix-list.
  876. ! zebra-0.8x
  877. ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  878. ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  879. ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
  880. ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  881. ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  882. ipv6 prefix-list 6bone-filter seq 30 deny any
  883. !
  884. * RIP configuration
  885. If you want to filter only default route (0.0.0.0/0) and permit other
  886. routes, it was hard to do that. Now `ip prefix-list' can be used for
  887. RIP route filtering.
  888. New statement:
  889. `distribute-list prefix PLIST_NAME (in|out) IFNAME'
  890. is added to ripd. So you can configure on eth0 interface accept all
  891. routes other than default routes.
  892. !
  893. router rip
  894. distribute-list prefix filter-default in eth0
  895. !
  896. ip prefix-list filter-default deny 0.0.0.0/0 le 0
  897. ip prefix-list filter-default permit any
  898. !
  899. * RIPng configuration
  900. Same change is done for ripngd. You can use `ipv6 prefix-list' for
  901. filtering.
  902. !
  903. router ripng
  904. distribute-list prefix filter-default in eth0
  905. !
  906. ipv6 prefix-list filter-default deny ::/0 le 0
  907. ipv6 prefix-list filter-default permit any
  908. !
  909. * BGP configuration
  910. So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
  911. done with traditional IPv4 peering statement like blow.
  912. !
  913. router bgp 7675
  914. neighbor 3ffe:506::1 remote-as 2500
  915. neighbor 3ffe:506::1 prefix-list 6bone-filter out
  916. !
  917. For separating configuration IPv4 and IPv6, and for retaining Cisco
  918. configuration compatibility, now IPv6 configuration is done by IPv6
  919. specific statement. IPv6 BGP configuration is done by statement which
  920. start from `ipv6 bgp'.
  921. !
  922. router bgp 7675
  923. !
  924. ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
  925. ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
  926. !
  927. At the same time some IPv6 specific commands are deleted from IPv4
  928. configuration.
  929. o redistribute ripng
  930. o redistribute ospf6
  931. o neighbor PEER version BGP_VERSION
  932. o neighbor PEER interface IFNAME
  933. Those commands are only accepted as like below.
  934. o ipv6 bgp redistribute ripng
  935. o ipv6 bgp redistribute ospf6
  936. o ipv6 bgp neighbor PEER version BGP_VERSION
  937. o ipv6 bgp neighbor PEER interface IFNAME
  938. And below new commands are added.
  939. o ipv6 bgp network IPV6_PREFIX
  940. o ipv6 bgp redistribute static
  941. o ipv6 bgp redistribute connected
  942. o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
  943. o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
  944. o ipv6 bgp neighbor PEER description DESCRIPTION
  945. o ipv6 bgp neighbor PEER shutdown
  946. o ipv6 bgp neighbor PEER route-reflector-client
  947. o ipv6 bgp neighbor PEER update-source IFNAME
  948. o ipv6 bgp neighbor PEER next-hop-self

  955. o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
  956. o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
  957. o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
  958. And some utility commands are introduced.
  959. o clear ipv6 bgp [PEER]
  960. o show ipv6 bgp neighbors [PEER]
  961. o show ipv6 bgp summary
  962. I hope these changes are easy to understand for current Zebra users...
  963. * To restrict connection to VTY interface.
  964. It used to be both IPv4 and IPv6 filter can be specified with one
  965. access-list. Then the access-list can be appried to VTY interface
  966. with `access-class' stetement in `line vty' node. Below is example in
  967. zebra-0.7x.
  968. !
  969. access-list local-only permit 127.0.0.1/32
  970. access-list local-only permit ::1/128
  971. access-list local-only deny any
  972. !
  973. line vty
  974. access-class local-only
  975. !
  976. Now IPv4 and IPv6 filter have each name space. It is not possible to
  977. specify IPv4 and IPv6 filter with one access-list. For setting IPv6
  978. access-list in `line vty', `ipv6 access-class' statement is
  979. introduced. Let me show the configuration in zebra-0.8x.
  980. !
  981. access-list local-only permit 127.0.0.1/32
  982. access-list local-only deny any
  983. !
  984. ipv6 access-list local-only permit ::1/128
  985. ipv6 access-list local-only dny any
  986. !
  987. line vty
  988. access-class local-only
  989. ipv6 access-class local-only
  990. !
  991. * route-map
  992. New IPv6 related route-map match commands are added.
  993. o match ipv6 address
  994. o match ipv6 next-hop
  995. Please change your configuration if you use IP match statement for
  996. IPv6 route.
  997. zebra-0.7x config
  998. =================
  999. !
  1000. access-list all permit any
  1001. !
  1002. route-map set-nexthop permit 10
  1003. match ip address all
  1004. set ipv6 next-hop global 3ffe:506::1
  1005. set ipv6 next-hop local fe80::cbb5:591a
  1006. !
  1007. zebra-0.8x config

  1015. set ipv6 next-hop local fe80::cbb5:591a
  1016. !
  1017. * zebra connection
  1018. Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
  1019. when the connection fail. Those daemons try to connect zebra every 10
  1020. seconds first three trial, then the interval changed to 60 seconds.
  1021. After all, if ten connections are fail, protocol daemon give up the
  1022. connection to the zebra daemon.
  1023. * SNMP support (is not yet finished)
  1024. Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
  1025. agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
  1026. and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
  1027. compiled with ucd-snmp-3.6.2.
  1028. After applying the patch to ucd-snmp-4.0.1, please configure it with
  1029. SMUX module.
  1030. % configure --with-mib-modules=smux
  1031. After compile & install ucd-snmp-4.0.1, you will need to configure
  1032. smuxpeer. I'm now using below configuration.
  1033. /usr/local/share/snmp/snmpd.conf
