  1. Note: this file lists major user-visible changes only.
  2. * Changes in Quagga 0.99.24
  3. User-visible changes:
  4. - [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing.
  5. - [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route
  6. reflector setups.
  7. - [bgpd] route-maps have a new action "set ipv6 next-hop peer-address"
  8. - [bgpd] route-maps have a new action "set as-path prepend last-as"
  9. - [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was
  10. touched up significantly. Please report possible bugs.
  11. - [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP)
  12. - [zebra] Multicast RIB support has been extended. It still is IPv4 only.
  13. - [zebra] "no link-detect" is now printed in configurations since it won't
  14. be the default anymore soon. To retain current behaviour, re-save your
  15. configuration after updating to 0.99.24.
  16. Distributor-visible changes:
  17. - --enable-pimd is added to enable pimd. It is considered experimental, though
  18. unless the distribution target is embedded systems with little flash, there
  19. is no reason to not include it in packages.
  20. - --disable-ipv6 no longer exists as an option. It's 2015, your C library
  21. really needs to have IPv6 support by now.
  22. - --disable-netlink no longer exists as an option. It didn't work anyway.
  23. - --disable-solaris no longer exists as an option. It only controlled some
  24. init scripts.
  25. - --enable-isisd is now the default.
  26. - mrlg.cgi is no longer included (it was severely outdated). It can be found
  27. independently at http://mrlg.op-sec.us/
  28. - build on Linux with the musl C library should now work
  29. * Changes in Quagga 0.99.23
  30. Known issues:
  31. - [bgpd] setting an extcommunity in a route map on a route that already has
  32. an extcommunity attribute will cause bgpd to crash. This issue will be
  33. fixed in a followup minor release.
  34. User-visible changes:
  35. - [lib] Performance enhancements on hashes and timers.
  36. - [bgpd] New feature: iBGP TTL security.
  37. - [bgpd] New feature: relaxed bestpath criteria for multipath and improved
  38. display of multipath routes in "show ip bgp". Scripts parsing this output
  39. may need to be updated.
  40. - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate
  41. IPv4 nexthop by looking at the interface.
  42. - [ospf6d] A large amount of changes has been merged for ospf6d. Careful
  43. evaluation prior to deployment is recommended.
  44. - [zebra] Recursive route support has been overhauled. Scripts parsing
  45. "show ip route" output may need adaptation.
  46. - [zebra] IPv6 address management has been improved regarding tentative
  47. addresses. This is visible in that a freshly configured address will not
  48. immediately be marked as usable.
  49. - [*] a lot of bugs have been fixed, please refer to the git log
  50. * Changes in Quagga 0.99.22
  51. - [bgpd] The semantics of default-originate route-map have changed.
  52. The route-map is now used to advertise the default route conditionally.
  53. The old behaviour which allowed to set attributes on the originated
  54. default route is no longer supported.
  55. - [bgpd] There is now a replace-as option to neighbor ... local-as ...
  56. no-prepend. For details, refer to the user documentation.
  57. - [zebra] An FPM interface has been added. This provides an alternate
  58. interface to routing information and is geared at OpenFlow & co.
  59. - [snmp] AgentX is now supported; the old smux backend is considered
  60. deprecated. ospf6d has also had OSPFV3-MIB added.
  61. - [*] several issues with configuration save/load/apply have been fixed,
  62. in particular on ospf "max-metric router-lsa administrative" and
  63. "distribute-list", bgpd "no neighbor activate", isisd "metric-style",
  64. - [*] a lot of bugs have been fixed, please refer to the git log
  65. * Changes in Quagga 0.99.21
  66. - [bgpd] BGP multipath support has been merged
  67. - [bgpd] SAFI (Multicast topology) support has been extended to propagate
  68. the topology to zebra.
  69. - [bgpd] AS path limit functionality has been removed
  70. - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing
  71. protocol has been merged.
  72. - [isisd] a major overhaul has been picked up. Please note that isisd is
  73. STILL NOT SUITABLE FOR PRODUCTION USE.
  74. - [*] a lot of bugs have been fixed, please refer to the git log
  75. * Changes in Quagga 0.99.10
  76. - [bgpd] 4-byte AS support added
  77. - [bgpd] MRT format changes to version 2. Those relying on
  78. bgpd MRT table dumps may need to update their tools.
  79. - [bgpd] Added new route-map set statement: "as-path exclude"
  80. - Zebra RIB updates queue has evolved into a multi-level
  81. structure to address RIB consistency issues.
  82. * Changes in Quagga 0.99.2
  83. - [bgpd] Work queues added to bgpd to split up update processing,
  84. particularly beneficial when a peer session goes down. AS_PATH
  85. parsing rewritten to be clearer, more robust and ready for 4-byte.
  86. - [ripd] Simple authentication is no longer the default authentication
  87. mode for ripd. The default is now no-authentication. Any setups which
  88. used simple authentication will probably need to update their
  89. configuration manually.
  90. - [ospfd] 1s dead-interval with sub-second Hellos feature added.
  91. SPF timers now specified in milliseconds, and with adaptive
  92. hold-time support. RFC3137 Stub-router support added. Default ABR
  93. type is now 'cisco'.
  94. - Solaris least privileges support added.
  95. * Changes in Quagga 0.99.1
  96. - Zserv is now buffered via threads and non-blocking in most cases for both
  97. clients and zebra, which should improve responsiveness of daemons when
  98. they must send many messages to zebra.
  99. - 'show thread cpu' now displays both cpu+system and wall-clock time,
  100. where getrusage() is available.
  101. - Background threads added and workqueue API added, with a
  102. 'show work-queues' command. Thread scheduling improved slightly.
  103. - Zebra now has a work-queue for RIB processing. See 'show work-queues' in
  104. the zebra daemon vty.
  105. - Support for interface renaming on Linux netlink systems.
  106. - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip
  107. route-source" command.
  108. - Automatic logging of backtraces should daemons crash to assist in
  109. diagnosis. See the documentation for more information on configuring
  110. logging correctly, and set --enable-gcc-rdynamic if compiling with gcc.
  111. * Changes in Quagga 0.98.0
  112. - Logging facilities upgraded. One can now specify a severity level
  113. for each logging destination. And a new "show logging" command gives
  114. thorough information on the current logging system configuration.
  115. - Watchquagga daemon added. This is not well tested yet. Please try
  116. monitor mode first before enabling restart features. It is important
  117. to make sure that the various timers are configured with appropriate
  118. values for your site.
  119. - BGP route-server support added. See the texinfo documentation.
  120. - OSPF API initialisation is disabled by default even if compiled in. You
  121. can enable it with -a/--apiserver command line switch.
  122. - "write-config integrated" vtysh command replaced with "service
  123. integrated-vtysh-config" command.
  124. - Router id is now handled by zebra daemon and all daemons receive changes
  125. from it. Router id can be overriden in daemons' configurations of course.
  126. To fix common router id in zebra daemon you can either install non-127
  127. address on loopback or use "router-id x.x.x.x" command.
  128. - "secondary" keyword is removed from ip address configuration. All
  129. supported OS'es have their own vision what's secondary address and
  130. how to handle it.
  131. - Zebra no longer enables forwarding by default. If you rely on zebra to
  132. enable forwarding make sure to add '<ip|ip6> forwarding' statements
  133. to your zebra configuration file.
  134. - All libraries are built and used shared, on platforms where libtool
  135. supports shared libraries.
  136. - Router advertisement syntax is changed. In usual cases (if you didn't do
  137. any fancy stuff) it's enough to change lines in configuration from:
  138. "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link"
  139. to:
  140. "ipv6 nd prefix X:X:X:X::/X"
  141. All router advertisement options are documented in texi documentation.
  142. - --enable-nssa configure switch is removed. NSSA support is stable enough.
  143. - Daemons don't look at current directory for config file any more.
  144. * Changes in Quagga 0.96.5
  145. - include files are installed in $(prefix)/include/quagga. Programs
  146. building against these includes should -I$(prefix)/include and e.g.
  147. #include <quagga/routemap.h>
  148. - New option --enable-exampledir puts example files in a separate
  149. directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules
  150. compliance.
  151. - New configure options --enable-configfile-mask and
  152. --enable-logfile-mask to set umask values for config and log
  153. values. Masks default to 0600, matching previous behavior.
  154. - Import current CVS isisd from SourceForge, then merge it with
  155. the Quagga's Framework.
  156. * Changes in Quagga 0.96.4
  157. - Further fixes to ospfd, some relating to the PtP revert. Interface
  158. lookups should be a lot more robust now.
  159. - Fix for a remote triggerable crash in vty layer.
  160. - Improvements to ripd, and addition of split horizon support.
  161. - Improved bgpd table support, now dumps at time of day intervals rather
  162. than time from startup intervals. Much improved support for IPv6 table
  163. dumps. show commands for views improved.
  164. * Changes in Quagga 0.96.3
  165. - revert the 'generic PtP' patch. Means Quagga will no longer work with
  166. FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs
  167. which the PtP patch introduced.
  168. * Changes in Quagga 0.96.2
  169. - Fix crash in ospfd
  170. * Changes in Quagga 0.96.1
  171. - Iron out problem with the privileges definitions
  172. * Changes in Quagga 0.96
  173. - Privilege support, daemons now run with the minimal privileges needed, see
  174. the documentation for details.
  175. - NSSA ABR support in ospfd.
  176. - OSPF-API support merged in.
  177. - 6WIND patch merged in.

  203. ** IPv4 multicast and IPv6 unicast configuration is changed to so
  204. called new config. All of AFI and SAFI specific configuration is
  205. moved to "address-family" node. When you have many IPv6 only
  206. configuration, you will see many "no neighbor X:X::X:X activate" line
  207. in your configuration to disable IPv4 unicast NLRI exchange. In that
  208. case please use "no bgp default ipv4-unicast" command to suppress the
  209. output. Until zebra-0.93, old config is still left for compatibility.

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

  396. has it's AS number in the first AS number in AS sequence.
  397. ** New route-map command "set community-delete COMMUNITY-LIST" is
  398. added. Community matched the CoMMUNITY-LIST is removed from the
  399. community.
  400. ** BGP-MIB implementation is finished.
  401. ** When BGP connection comes from unconfigured IP address, close
  402. socket immediately.
  403. ** Do not compare router ID when the routes comes from EBGP peer.
  404. When originator ID is same, take shorter cluster-list route. If
  405. cluster-list is same take smaller IP address neighbor's route.
  406. ** Add "bgp bestpath as-path ignore" command. When this option is
  407. set, do not concider AS path length when route selection.
  408. ** Add "bgp bestpath compare-routerid". When this option is set,
  409. compare router ID when the routes comes from EBGP peer.
  410. ** Add "bgp deterministic-med" process.
  411. ** BGP flap dampening feature is added.
  412. ** When IBGP nexthop is changed, it is reflected to RIB.
  413. ** Change "neighbor route-refresh" command to "neighbor capability
  414. route-refresh".
  415. * Changes in ripd
  416. ** Change "match ip next-hop" argument from IP address to access-list
  417. name.
  418. ** "no ip rip (send|receive)" command accept version number argument.
  419. ** Memory leak related classfull network generation is fixed.
  420. ** When a route is in garbage collection process (invalid with metric
  421. 16) and a router receives the same route with valid metric then route
  422. was not installed into zebra rib, but only into ripd rib. Moreover ,
  423. it will never get into zebra rib, because ripd wrongly assumes it's
  424. already there.
  425. * Change in ospfd
  426. ** Fix bug of refreshing default route.
  427. ** --enable-nssa turn on undergoing NSSA feature.

  431. ** Add nexthop to OSPF path only when it is not there.
  432. ** When there is no DR on network (suppose you have only one router
  433. with interface priority 0). It's router LSA does not contain the link
  434. information about this network.
  435. ** When you change a priority of interface from/to 0
  436. ISM_NeighborChange event should be scheduled in order to elect new
  437. DR/BDR on the network.
  438. ** When we add some LSA into retransmit list we need to check whether
  439. the present old LSA in retransmit list is not more recent than the new
  440. one.
  441. ** In states Loading and Full the slave must resend its last Database
  442. Description packet in response to duplicate Database Description
  443. packets received from the master. For this reason the slave must wait
  444. RouterDeadInterval seconds before freeing the last Database
  445. Description packet. Reception of a Database Description packet from
  446. the master after this interval will generate a SeqNumberMismatch
  447. neighbor event. RFC2328 Section 10.8
  448. ** Virtual link can not configured in stub area.
  449. ** Clear a ls_upd_queue queue of the interface when interface goes
  450. down.

  459. ** Clear cryptographic sequence number when neighbor status is changed
  460. to NSM down.
  461. ** Make Summary LSA's origination and refreshment as same as other
  462. type of LSA.
  463. ** New OSPF pakcet read method. Now maximum packet length may be 65535

  478. ** Fix bug of using unavailable route.
  479. * Changes in vtysh
  480. ** route-map and access-list configuration is merged into one
  481. configuration.
  482. ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
  483. memory" in vtysh will write whole configuration to this file.
  484. ** When -b option is specified to vtysh, vtysh read
  485. /usr/local/etc/Zebra.conf file then pass the confuguration to proper
  486. protocol daemon. So make all protocol daemon's configuration file

  772. ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
  773. <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
  774. "X:X::X:X/M" for IPv6 prefix. You can use it like this.
  775. DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
  776. ** VTY configuration is locked during configuration. This is for
  777. avoiding unconditional crush from two terminals modify the
  778. configuration at the same time. "who" command shows which termnal
  779. lock the configuration. VTY which has '*' character at the head of
  780. line is locking the configuration.
  781. ** Old logging functions are removed. Functions like

  821. "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
  822. * Changes in zebra-0.83
  823. * bgpd
  824. ** Serious bug fix about fetching global and link-local address at the
  825. same time. Due to this bug, corrupted IPv6 prefix is generated. If
  826. you uses bgpd for BGP-4+ please update to this version. The bug is
  827. introduced in zebra-0.82.
  828. ** When bgpd send Notify message, don't use thread manager. It is now
  829. send to neighbor immediately.
  830. * Changes in zebra-0.82

  832. <handler@sub-rosa.com>.
  833. ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
  834. Please specify --enable-mbgp to configure script. This option will be
  835. removed in the future and MBGP support will be default.
  836. * Changes in zebra
  837. ** When interface goes down, withdraw connected routes from routing
  838. table. When interface goes up, restore the routes to the routing
  839. table.
  840. ** `show interface' show interface's statistics on Linux and BSD with
  841. routing socket.
  842. ** Now zebra can get MTU value on BSDI/OS.
  843. * Changes in bgpd

  860. ** SNMP support is disabled in default.--enable-snmp option is added
  861. to configure script.
  862. * Changes in bgpd
  863. ** Fix FSM bug which introduced in zebra-0.80.
  864. * Changes in zebra-0.80
  865. * access-list
  866. New access-list name space `ipv6 access-list' is added. At the same
  867. time, `access-list' statemant only accepts IPv4 prefix. Please be
  868. careful if you use IPv6 filtering. You will need to change your
  869. configuration. For IPv6 filtering please use `ipv6 access-list'.
  870. As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
  871. filtering.
  872. ! zebra-0.7x
  873. access-list DML-net permit 203.181.89.0/24
  874. access-list DML-net permit 3ffe:506::0/32
  875. access-list DML-net deny any
  876. !
  877. Above configuration is not valid for zebra-08x. Please add `ipv6'
  878. before 'access-list' when you configure IPv6 filtering.
  879. ! zebra-0.8x
  880. access-list DML-net permit 203.181.89.0/24
  881. access-list DML-net deny any
  882. !
  883. ipv6 access-list DML-net permit 3ffe:506::0/32
  884. ipv6 access-list DML-net deny any
  885. !
  886. * prefix-list
  887. And also new prefix-list name space `ipv6 prefix-list' is added. It
  888. is the same as the change of `access-list'. `ip prefix-list' now only
  889. accept IPv4 prefix. It was source of confusion that `ip prefix-list'
  890. can be used both IPv4 and IPv6 filtering. Now name space is separated
  891. to clear the meaning of the filter.
  892. If you use `ip prefix-list' for IPv6 filtering, please change the
  893. stetement.
  894. ! zebra-0.7x
  895. ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  896. ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  897. ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
  898. ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  899. ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  900. ip prefix-list 6bone-filter seq 30 deny any
  901. !
  902. Now user can explicitly configure it as IPv6 prefix-list.
  903. ! zebra-0.8x
  904. ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  905. ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  906. ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
  907. ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  908. ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  909. ipv6 prefix-list 6bone-filter seq 30 deny any
  910. !
  911. * RIP configuration
  912. If you want to filter only default route (0.0.0.0/0) and permit other
  913. routes, it was hard to do that. Now `ip prefix-list' can be used for
  914. RIP route filtering.
  915. New statement:
  916. `distribute-list prefix PLIST_NAME (in|out) IFNAME'
  917. is added to ripd. So you can configure on eth0 interface accept all
  918. routes other than default routes.
  919. !
  920. router rip
  921. distribute-list prefix filter-default in eth0
  922. !
  923. ip prefix-list filter-default deny 0.0.0.0/0 le 0
  924. ip prefix-list filter-default permit any
  925. !
  926. * RIPng configuration
  927. Same change is done for ripngd. You can use `ipv6 prefix-list' for
  928. filtering.
  929. !
  930. router ripng
  931. distribute-list prefix filter-default in eth0
  932. !
  933. ipv6 prefix-list filter-default deny ::/0 le 0
  934. ipv6 prefix-list filter-default permit any
  935. !
  936. * BGP configuration
  937. So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
  938. done with traditional IPv4 peering statement like blow.
  939. !
  940. router bgp 7675
  941. neighbor 3ffe:506::1 remote-as 2500
  942. neighbor 3ffe:506::1 prefix-list 6bone-filter out
  943. !
  944. For separating configuration IPv4 and IPv6, and for retaining Cisco
  945. configuration compatibility, now IPv6 configuration is done by IPv6
  946. specific statement. IPv6 BGP configuration is done by statement which
  947. start from `ipv6 bgp'.
  948. !
  949. router bgp 7675
  950. !
  951. ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
  952. ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
  953. !
  954. At the same time some IPv6 specific commands are deleted from IPv4
  955. configuration.
  956. o redistribute ripng
  957. o redistribute ospf6
  958. o neighbor PEER version BGP_VERSION
  959. o neighbor PEER interface IFNAME
  960. Those commands are only accepted as like below.
  961. o ipv6 bgp redistribute ripng
  962. o ipv6 bgp redistribute ospf6
  963. o ipv6 bgp neighbor PEER version BGP_VERSION
  964. o ipv6 bgp neighbor PEER interface IFNAME
  965. And below new commands are added.
  966. o ipv6 bgp network IPV6_PREFIX
  967. o ipv6 bgp redistribute static
  968. o ipv6 bgp redistribute connected
  969. o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
  970. o ipv6 bgp neighbor PEER ebgp-multihop [TTL]

  984. o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
  985. And some utility commands are introduced.
  986. o clear ipv6 bgp [PEER]
  987. o show ipv6 bgp neighbors [PEER]
  988. o show ipv6 bgp summary
  989. I hope these changes are easy to understand for current Zebra users...
  990. * To restrict connection to VTY interface.
  991. It used to be both IPv4 and IPv6 filter can be specified with one
  992. access-list. Then the access-list can be appried to VTY interface
  993. with `access-class' stetement in `line vty' node. Below is example in
  994. zebra-0.7x.
  995. !
  996. access-list local-only permit 127.0.0.1/32
  997. access-list local-only permit ::1/128
  998. access-list local-only deny any
  999. !
  1000. line vty
  1001. access-class local-only
  1002. !
  1003. Now IPv4 and IPv6 filter have each name space. It is not possible to
  1004. specify IPv4 and IPv6 filter with one access-list. For setting IPv6
  1005. access-list in `line vty', `ipv6 access-class' statement is
  1006. introduced. Let me show the configuration in zebra-0.8x.
  1007. !
  1008. access-list local-only permit 127.0.0.1/32
  1009. access-list local-only deny any
  1010. !
  1011. ipv6 access-list local-only permit ::1/128
  1012. ipv6 access-list local-only dny any
  1013. !
  1014. line vty
  1015. access-class local-only
  1016. ipv6 access-class local-only
  1017. !
  1018. * route-map
  1019. New IPv6 related route-map match commands are added.

  1044. * zebra connection
  1045. Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
  1046. when the connection fail. Those daemons try to connect zebra every 10
  1047. seconds first three trial, then the interval changed to 60 seconds.
  1048. After all, if ten connections are fail, protocol daemon give up the
  1049. connection to the zebra daemon.
  1050. * SNMP support (is not yet finished)
  1051. Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
  1052. agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
  1053. and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
  1054. compiled with ucd-snmp-3.6.2.
  1055. After applying the patch to ucd-snmp-4.0.1, please configure it with
  1056. SMUX module.
  1057. % configure --with-mib-modules=smux
  1058. After compile & install ucd-snmp-4.0.1, you will need to configure
  1059. smuxpeer. I'm now using below configuration.
  1060. /usr/local/share/snmp/snmpd.conf
  1061. ================================
  1062. smuxpeer 1.3.6.1.6.3.1 test
