  132. should be installed into routing table instead of local network.
  133. ** Metric value is reflected to kernel routing table.
  134. ** "show ip route" display uptime of RIP,OSPF,BGP routes.
  135. ** New RIB implementation is added.
  136. Now we have enhanced RIB (routing information base) implementation in
  137. zebra. New RIB has many new features and fixed some bugs which exist
  138. in old RIB code.
  139. *** Static route with distance value
  140. Static route can be specified with administrative distance. The
  141. distance value 255 means it is not installed into the kernel.
  142. Default value of distance for static route is 1.
  143. ip route A.B.C.D/M A.B.C.D <1-255>
  144. ip route A.B.C.D/M IFNAME <1-255>
  145. If the least distance value's route's nexthop are unreachable,
  146. select the least distance value route which has reachable nexthop is
  147. selected.
  148. ip route 0.0.0.0/0 10.0.0.1
  149. ip route 0.0.0.0/0 11.0.0.1 2
  150. In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
  151. reachable. The route with nexthop 11.0.0.1 will be installed into
  152. forwarding table.
  153. zebra> show ip route
  154. S>* 0.0.0.0/0 [2/0] via 11.0.0.1
  155. S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
  156. If the nexthop is unreachable "inactive" is displayed. You can
  157. specify any string to IFNAME. There is no need of the interface is
  158. there when you configure the route.
  159. ip route 1.1.1.1/32 ppp0
  160. When ppp0 comes up, the route is installed properly.
  161. *** Multiple nexthop routes for one prefix
  162. Multiple nexthop routes can be specified for one prefix. Even the
  163. kernel support only one nexthop for one prefix user can configure
  164. multiple nexthop.
  165. When you configure routes like below, prefix 10.0.0.1 has three
  166. nexthop.
  167. ip route 10.0.0.1/32 10.0.0.2
  168. ip route 10.0.0.1/32 10.0.0.3
  169. ip route 10.0.0.1/32 eth0
  170. If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
  171. is reachable, then the last route is installed into the kernel.
  172. zebra> show ip route
  173. S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
  174. via 10.0.0.3 inactive
  175. * is directly connected, eth0
  176. '*' means this nexthop is installed into the kernel.
  177. *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
  178. When the kernel support multipath, zebra can install multipath
  179. routes into the kernel. Before doing that please make it sure that
  180. setting --enable-multipath=ARG to configure script. ARG must be digit
  181. value. When specify 0 to ARG, there is no limitation of the number
  182. of the multipath. Currently only GNU/Linux with netlink interface is
  183. supported.
  184. ip route 10.0.0.1/32 10.0.0.2
  185. ip route 10.0.0.1/32 10.0.0.3
  186. ip route 10.0.0.1/32 eth0
  187. zebra> show ip route
  188. S>* 10.0.0.1/32 [1/0] via 10.0.0.2
  189. * via 10.0.0.3
  190. is directly connected, eth0
  191. *** Kernel message delete installed route.
  192. After zebra install static or dynamic route into the kernel.
  193. R>* 0.0.0.0/0 [120/3] via 10.0.0.1
  194. If you delete this route outside zebra, old zebra does not reinstall
  195. route again. Now the route is re-processed and properly reinstall the
  196. static or dynamic route into the kernel.
  197. ** GNU/Linux netlink socket handling is improved to fix race condition
  198. between kernel message and user command responce.
  199. * Changes in bgpd
  200. ** Add show neighbor's routes command.
  201. "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
  202. "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
  203. "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
  204. "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
  205. ** BGP passive peer support problem is fixed.
  206. ** Redistributed IGP nexthop is passed to BGP nexthop.
  207. ** On multiaccess media, if the nexthop is reachable nexthop is passed
  208. as it is.
  209. ** Remove zebra-0.88 compatibility commands.
  210. "match ip prefix-list WORD"
  211. "match ipv6 prefix-list WORD"
  212. Instead of above please use below commands.
  213. "match ip address prefix-list WORD"
  214. "match ipv6 address prefix-list WORD"
  215. ** Fix bug of holdtimer is not reset when bgp cleared.
  216. ** "show ip bgp summary" display peer establish/drop count.
  217. ** Change "match ip next-hop" argument from IP address to access-list
  218. name.
  219. ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
  220. has it's AS number in the first AS number in AS sequence.
  221. ** New route-map command "set community-delete COMMUNITY-LIST" is
  222. added. Community matched the CoMMUNITY-LIST is removed from the
  223. community.
  224. ** BGP-MIB implementation is finished.
  225. ** When BGP connection comes from unconfigured IP address, close
  226. socket immediately.
  227. ** Do not compare router ID when the routes comes from EBGP peer.
  228. When originator ID is same, take shorter cluster-list route. If
  229. cluster-list is same take smaller IP address neighbor's route.
  230. ** Add "bgp bestpath as-path ignore" command. When this option is
  231. set, do not concider AS path length when route selection.
  232. ** Add "bgp bestpath compare-routerid". When this option is set,
  233. compare router ID when the routes comes from EBGP peer.
  234. ** Add "bgp deterministic-med" process.
  235. ** BGP flap dampening feature is added.
  236. ** When IBGP nexthop is changed, it is reflected to RIB.
  237. ** Change "neighbor route-refresh" command to "neighbor capability
  238. route-refresh".
  239. * Changes in ripd
  240. ** Change "match ip next-hop" argument from IP address to access-list
  241. name.
  242. ** "no ip rip (send|receive)" command accept version number argument.
  243. ** Memory leak related classfull network generation is fixed.
  244. ** When a route is in garbage collection process (invalid with metric
  245. 16) and a router receives the same route with valid metric then route

  668. ** Add capability option support based upon
  669. draft-ietf-idr-bgp4-cap-neg-04.txt.
  670. ** Add `show ipv6 bgp prefix-list' command.
  671. ** Check self AS appeared in received routes.
  672. ** redistribute route-map support is added.
  673. ** BGP packet dump feature compatible with MRT.
  674. * Changes in ripd
  675. ** Fix bug of `timers basic' command's argument format.
  676. * Changes in ripngd
  677. ** Calculate max RTE using interface's MTU value.
  678. * Changes in ospfd
  679. ** Some correction to LSU processing.
  680. ** Add check for lsa->refresh_list.
  681. * Changes in ospf6d
  682. ** Many debug feature is added.
  683. * Changes in zebra-0.81
  684. ** SNMP support is disabled in default.--enable-snmp option is added
  685. to configure script.
  686. * Changes in bgpd
  687. ** Fix FSM bug which introduced in zebra-0.80.
  688. * Changes in zebra-0.80
  689. * access-list
  690. New access-list name space `ipv6 access-list' is added. At the same
  691. time, `access-list' statemant only accepts IPv4 prefix. Please be
  692. careful if you use IPv6 filtering. You will need to change your
  693. configuration. For IPv6 filtering please use `ipv6 access-list'.
  694. As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
  695. filtering.
  696. ! zebra-0.7x
  697. access-list DML-net permit 203.181.89.0/24
  698. access-list DML-net permit 3ffe:506::0/32
  699. access-list DML-net deny any
  700. !
  701. Above configuration is not valid for zebra-08x. Please add `ipv6'
  702. before 'access-list' when you configure IPv6 filtering.
  703. ! zebra-0.8x
  704. access-list DML-net permit 203.181.89.0/24
  705. access-list DML-net deny any
  706. !
  707. ipv6 access-list DML-net permit 3ffe:506::0/32
  708. ipv6 access-list DML-net deny any
  709. !
  710. * prefix-list
  711. And also new prefix-list name space `ipv6 prefix-list' is added. It
  712. is the same as the change of `access-list'. `ip prefix-list' now only
  713. accept IPv4 prefix. It was source of confusion that `ip prefix-list'
  714. can be used both IPv4 and IPv6 filtering. Now name space is separated
  715. to clear the meaning of the filter.
  716. If you use `ip prefix-list' for IPv6 filtering, please change the
  717. stetement.
  718. ! zebra-0.7x
  719. ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  720. ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  721. ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
  722. ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  723. ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  724. ip prefix-list 6bone-filter seq 30 deny any
  725. !
  726. Now user can explicitly configure it as IPv6 prefix-list.
  727. ! zebra-0.8x
  728. ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
  729. ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
  730. ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
  731. ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
  732. ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
  733. ipv6 prefix-list 6bone-filter seq 30 deny any
  734. !
  735. * RIP configuration
  736. If you want to filter only default route (0.0.0.0/0) and permit other
  737. routes, it was hard to do that. Now `ip prefix-list' can be used for
  738. RIP route filtering.
  739. New statement:
  740. `distribute-list prefix PLIST_NAME (in|out) IFNAME'
  741. is added to ripd. So you can configure on eth0 interface accept all
  742. routes other than default routes.
  743. !
  744. router rip
  745. distribute-list prefix filter-default in eth0
  746. !
  747. ip prefix-list filter-default deny 0.0.0.0/0 le 0
  748. ip prefix-list filter-default permit any
  749. !
  750. * RIPng configuration
  751. Same change is done for ripngd. You can use `ipv6 prefix-list' for
  752. filtering.
  753. !
  754. router ripng
  755. distribute-list prefix filter-default in eth0
  756. !
  757. ipv6 prefix-list filter-default deny ::/0 le 0
  758. ipv6 prefix-list filter-default permit any
  759. !
  760. * BGP configuration
  761. So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
  762. done with traditional IPv4 peering statement like blow.
  763. !
  764. router bgp 7675
  765. neighbor 3ffe:506::1 remote-as 2500
  766. neighbor 3ffe:506::1 prefix-list 6bone-filter out
  767. !
  768. For separating configuration IPv4 and IPv6, and for retaining Cisco
  769. configuration compatibility, now IPv6 configuration is done by IPv6
  770. specific statement. IPv6 BGP configuration is done by statement which
  771. start from `ipv6 bgp'.
  772. !
  773. router bgp 7675
  774. !
  775. ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
  776. ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
  777. !
  778. At the same time some IPv6 specific commands are deleted from IPv4
  779. configuration.
  780. o redistribute ripng
  781. o redistribute ospf6
  782. o neighbor PEER version BGP_VERSION
  783. o neighbor PEER interface IFNAME
  784. Those commands are only accepted as like below.
  785. o ipv6 bgp redistribute ripng
  786. o ipv6 bgp redistribute ospf6
  787. o ipv6 bgp neighbor PEER version BGP_VERSION
  788. o ipv6 bgp neighbor PEER interface IFNAME
  789. And below new commands are added.
  790. o ipv6 bgp network IPV6_PREFIX
  791. o ipv6 bgp redistribute static
  792. o ipv6 bgp redistribute connected
  793. o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
  794. o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
  795. o ipv6 bgp neighbor PEER description DESCRIPTION
  796. o ipv6 bgp neighbor PEER shutdown

  806. o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
  807. o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
  808. o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
  809. And some utility commands are introduced.
  810. o clear ipv6 bgp [PEER]
  811. o show ipv6 bgp neighbors [PEER]
  812. o show ipv6 bgp summary
  813. I hope these changes are easy to understand for current Zebra users...
  814. * To restrict connection to VTY interface.
  815. It used to be both IPv4 and IPv6 filter can be specified with one
  816. access-list. Then the access-list can be appried to VTY interface
  817. with `access-class' stetement in `line vty' node. Below is example in
  818. zebra-0.7x.
  819. !
  820. access-list local-only permit 127.0.0.1/32
  821. access-list local-only permit ::1/128
  822. access-list local-only deny any
  823. !
  824. line vty
  825. access-class local-only
  826. !
  827. Now IPv4 and IPv6 filter have each name space. It is not possible to
  828. specify IPv4 and IPv6 filter with one access-list. For setting IPv6
  829. access-list in `line vty', `ipv6 access-class' statement is
  830. introduced. Let me show the configuration in zebra-0.8x.
  831. !
  832. access-list local-only permit 127.0.0.1/32
  833. access-list local-only deny any
  834. !
  835. ipv6 access-list local-only permit ::1/128
  836. ipv6 access-list local-only dny any
  837. !
  838. line vty
  839. access-class local-only
  840. ipv6 access-class local-only
  841. !
  842. * route-map
  843. New IPv6 related route-map match commands are added.
  844. o match ipv6 address
  845. o match ipv6 next-hop
  846. Please change your configuration if you use IP match statement for
  847. IPv6 route.
  848. zebra-0.7x config
  849. =================
  850. !
  851. access-list all permit any
  852. !
  853. route-map set-nexthop permit 10
  854. match ip address all
  855. set ipv6 next-hop global 3ffe:506::1
  856. set ipv6 next-hop local fe80::cbb5:591a
  857. !
  858. zebra-0.8x config
  859. =================
  860. !
  861. ipv6 access-list all permit any
  862. !
  863. route-map set-nexthop permit 10
  864. match ipv6 address all
  865. set ipv6 next-hop global 3ffe:506::1
  866. set ipv6 next-hop local fe80::cbb5:591a
  867. !
  868. * zebra connection
  869. Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
  870. when the connection fail. Those daemons try to connect zebra every 10
  871. seconds first three trial, then the interval changed to 60 seconds.
  872. After all, if ten connections are fail, protocol daemon give up the
  873. connection to the zebra daemon.
  874. * SNMP support (is not yet finished)
  875. Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
  876. agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
  877. and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
  878. compiled with ucd-snmp-3.6.2.
  879. After applying the patch to ucd-snmp-4.0.1, please configure it with
  880. SMUX module.
  881. % configure --with-mib-modules=smux
  882. After compile & install ucd-snmp-4.0.1, you will need to configure
  883. smuxpeer. I'm now using below configuration.
  884. /usr/local/share/snmp/snmpd.conf
  885. ================================
  886. smuxpeer 1.3.6.1.6.3.1 test
  887. Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
  888. coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
  889. * HUP signal treatment
  890. From zebra-0.80, ripd will reload it's configuration file when ripd
  891. receives HUP signal. Other daemon such as bgpd, ospfd will support
  892. HUP signal treatment soon.
  893. * Changes in zebra-0.79
  894. * Changes in zebra
  895. ** Broadcast address setting on Linux box bug is fixed.

  1009. ** Now `terminal length 0' means no line output control.
  1010. ** `line LINES' command deleted. Instead of this please use `terminal
  1011. length <0-512>'.
  1012. ** `terminal length <0-512>' is each vty specific configuration so it
  1013. can not be configured in the configuration file. If you want to
  1014. configure system wide line control, please use `service

  1054. ** Host route such as IPv4 with /32 mask and IPv6 with /128 mask
  1055. didn't set RTF_GATEWAY even it has gateway. This bug if fixed now.
  1056. * Changes in bgpd
  1057. ** `match as-path' argument is used to be specify AS PATH value itself
  1058. directly (e.g. ^$). But it is changed to specify `ip as-apth
  1059. access-list' name.
  1060. ** iBGP route handle works without getting error from the kernel.
  1061. ** `set aggregator as AS A.B.C.D' command is added to route-map.
