- ** "show ip route" display uptime of RIP,OSPF,BGP routes.
- ** New RIB implementation is added.
- Now we have enhanced RIB (routing information base) implementation in
- zebra. New RIB has many new features and fixed some bugs which exist
- in old RIB code.
- *** Static route with distance value
- Static route can be specified with administrative distance. The
- distance value 255 means it is not installed into the kernel.
- Default value of distance for static route is 1.
-
- ip route A.B.C.D/M A.B.C.D <1-255>
- ip route A.B.C.D/M IFNAME <1-255>
-
- If the least distance value's route's nexthop are unreachable,
- select the least distance value route which has reachable nexthop is
- selected.
-
- ip route 0.0.0.0/0 10.0.0.1
- ip route 0.0.0.0/0 11.0.0.1 2
-
- In this case, when 10.0.0.1 is unreachable and 11.0.0.1 is
- reachable. The route with nexthop 11.0.0.1 will be installed into
- forwarding table.
-
- zebra> show ip route
- S>* 0.0.0.0/0 [2/0] via 11.0.0.1
- S 0.0.0.0/0 [1/0] via 10.0.0.1 inactive
-
- If the nexthop is unreachable "inactive" is displayed. You can
- specify any string to IFNAME. There is no need of the interface is
- there when you configure the route.
-
- ip route 1.1.1.1/32 ppp0
-
- When ppp0 comes up, the route is installed properly.
- *** Multiple nexthop routes for one prefix
- Multiple nexthop routes can be specified for one prefix. Even the
- kernel support only one nexthop for one prefix user can configure
- multiple nexthop.
-
- When you configure routes like below, prefix 10.0.0.1 has three
- nexthop.
-
- ip route 10.0.0.1/32 10.0.0.2
- ip route 10.0.0.1/32 10.0.0.3
- ip route 10.0.0.1/32 eth0
-
- If there is no route to 10.0.0.2 and 10.0.0.3. And interface eth0
- is reachable, then the last route is installed into the kernel.
-
- zebra> show ip route
- S> 10.0.0.1/32 [1/0] via 10.0.0.2 inactive
- via 10.0.0.3 inactive
- * is directly connected, eth0
-
- '*' means this nexthop is installed into the kernel.
- *** Multipath (more than one nexthop for one prefix) can be installed into the kernel.
- When the kernel support multipath, zebra can install multipath
- routes into the kernel. Before doing that please make it sure that
- setting --enable-multipath=ARG to configure script. ARG must be digit
- value. When specify 0 to ARG, there is no limitation of the number
- of the multipath. Currently only GNU/Linux with netlink interface is
- supported.
-
- ip route 10.0.0.1/32 10.0.0.2
- ip route 10.0.0.1/32 10.0.0.3
- ip route 10.0.0.1/32 eth0
-
- zebra> show ip route
- S>* 10.0.0.1/32 [1/0] via 10.0.0.2
- * via 10.0.0.3
- is directly connected, eth0
- *** Kernel message delete installed route.
- After zebra install static or dynamic route into the kernel.
-
- R>* 0.0.0.0/0 [120/3] via 10.0.0.1
-
- If you delete this route outside zebra, old zebra does not reinstall
- route again. Now the route is re-processed and properly reinstall the
- static or dynamic route into the kernel.
- ** GNU/Linux netlink socket handling is improved to fix race condition
- between kernel message and user command responce.
- * Changes in bgpd
- ** Add show neighbor's routes command.
- "show ip bgp neighbors (A.B.C.D|X:X::X:X) routes"
- "show ip bgp ipv4 (unicast|multicast) neighbors (A.B.C.D|X:X::X:X) routes"
- "show ipv6 bgp neighbors (A.B.C.D|X:X::X:X) routes"
- "show ipv6 mbgp neighbors (A.B.C.D|X:X::X:X) routes"
- ** BGP passive peer support problem is fixed.
- ** Redistributed IGP nexthop is passed to BGP nexthop.
- ** On multiaccess media, if the nexthop is reachable nexthop is passed
- as it is.
- ** Remove zebra-0.88 compatibility commands.
- "match ip prefix-list WORD"
- "match ipv6 prefix-list WORD"
- Instead of above please use below commands.
- "match ip address prefix-list WORD"
- "match ipv6 address prefix-list WORD"
- ** Fix bug of holdtimer is not reset when bgp cleared.
- ** "show ip bgp summary" display peer establish/drop count.
- ** Change "match ip next-hop" argument from IP address to access-list
- name.
- ** When "bgp enforce-first-as" is enabled, check EBGP peer's update
- has it's AS number in the first AS number in AS sequence.
- ** New route-map command "set community-delete COMMUNITY-LIST" is
- added. Community matched the CoMMUNITY-LIST is removed from the
- community.
- ** BGP-MIB implementation is finished.
- ** When BGP connection comes from unconfigured IP address, close
- socket immediately.
- ** Do not compare router ID when the routes comes from EBGP peer.
- When originator ID is same, take shorter cluster-list route. If
- cluster-list is same take smaller IP address neighbor's route.
- ** Add "bgp bestpath as-path ignore" command. When this option is
- set, do not concider AS path length when route selection.
- ** Add "bgp bestpath compare-routerid". When this option is set,
- compare router ID when the routes comes from EBGP peer.
- ** Add "bgp deterministic-med" process.
- ** BGP flap dampening feature is added.
- ** When IBGP nexthop is changed, it is reflected to RIB.
- ** Change "neighbor route-refresh" command to "neighbor capability

- name.
- ** "no ip rip (send|receive)" command accept version number argument.
- ** Memory leak related classfull network generation is fixed.
- ** When a route is in garbage collection process (invalid with metric
- 16) and a router receives the same route with valid metric then route
- was not installed into zebra rib, but only into ripd rib. Moreover ,
- it will never get into zebra rib, because ripd wrongly assumes it's
- already there.
- * Change in ospfd
- ** Fix bug of refreshing default route.
- ** --enable-nssa turn on undergoing NSSA feature.
- ** Fix bug of Hello packet's option is not properly set when interface
- comes up.
- ** Reduce unconditional logging.
- ** Add nexthop to OSPF path only when it is not there.
- ** When there is no DR on network (suppose you have only one router
- with interface priority 0). It's router LSA does not contain the link
- information about this network.
- ** When you change a priority of interface from/to 0
- ISM_NeighborChange event should be scheduled in order to elect new
- DR/BDR on the network.
- ** When we add some LSA into retransmit list we need to check whether
- the present old LSA in retransmit list is not more recent than the new
- one.
- ** In states Loading and Full the slave must resend its last Database
- Description packet in response to duplicate Database Description
- packets received from the master. For this reason the slave must wait
- RouterDeadInterval seconds before freeing the last Database
- Description packet. Reception of a Database Description packet from
- the master after this interval will generate a SeqNumberMismatch
- neighbor event. RFC2328 Section 10.8
- ** Virtual link can not configured in stub area.
- ** Clear a ls_upd_queue queue of the interface when interface goes
- down.
- ** "no router ospf" unregister redistribution requests from zebra.

- "area A.B.C.D virtual-link A.B.C.D hello-interval <1-65535> retransmit-interval <3-65535> transmit-delay <1-65535> dead-interval <1-65535> message-digest-key <1-255> md5 KEY"
- "area A.B.C.D virtual-link A.B.C.D message-digest-key <1-255> md5 KEY"
- ** Clear cryptographic sequence number when neighbor status is changed
- to NSM down.

- should call refresh instead of originate.
- ** Install multipath information to zebra.
- ** Fix socket descriptor leak when system call failed.

- "show ipv6 ospf6 spf node", "show ipv6 ospf6 spf tree", "show ipv6
- ospf6 spf table" has been added.
- ** Change to do not send garbage route whose nexthop is not linklocal
- address.

- file. It is fixed.
- ** LSDB sync bug is fixed.
- ** Fix bug of using unavailable route.
- * Changes in vtysh
- ** route-map and access-list configuration is merged into one
- configuration.
- ** /usr/local/etc/Zebra.conf is integrated configuration file. "write
- memory" in vtysh will write whole configuration to this file.
- ** When -b option is specified to vtysh, vtysh read
- /usr/local/etc/Zebra.conf file then pass the confuguration to proper
- protocol daemon. So make all protocol daemon's configuration file
- empty then invoke all daemon. After that vtysh -b will setup saved
- configuration.

- ** IPv6 address and prefix parser is added to VTY by Toshiaki Takada
- <takada@zebra.org>. DEFUN string is "X:X::X:X" for IPv6 address,
- "X:X::X:X/M" for IPv6 prefix. You can use it like this.
- DEFUN (func, cmd, "neighbor (A.B.C.D|X:X::X:X) remote-as <1-65535>")
- ** VTY configuration is locked during configuration. This is for
- avoiding unconditional crush from two terminals modify the
- configuration at the same time. "who" command shows which termnal
- lock the configuration. VTY which has '*' character at the head of
- line is locking the configuration.
- ** Old logging functions are removed. Functions like
- log_open,log_close,openlog are deleted. Instead of that please use
- zlog_* functions. zvlog_* used in ospf6d are deleted also.

- "neighbor A.B.C.D soft-reconfiguration inbound" beforehand.
-
- * Changes in zebra-0.83
- * bgpd
- ** Serious bug fix about fetching global and link-local address at the
- same time. Due to this bug, corrupted IPv6 prefix is generated. If
- you uses bgpd for BGP-4+ please update to this version. The bug is
- introduced in zebra-0.82.
- ** When bgpd send Notify message, don't use thread manager. It is now
- send to neighbor immediately.
- * Changes in zebra-0.82
- ** Solaris 2.6 support is added by Michael Handler
- <handler@sub-rosa.com>.
- ** MBGP support is added by Robert Olsson <Robert.Olsson@data.slu.se>.
- Please specify --enable-mbgp to configure script. This option will be
- removed in the future and MBGP support will be default.
- * Changes in zebra
- ** When interface goes down, withdraw connected routes from routing
- table. When interface goes up, restore the routes to the routing
- table.
- ** `show interface' show interface's statistics on Linux and BSD with
- routing socket.
- ** Now zebra can get MTU value on BSDI/OS.
- * Changes in bgpd

- ** SNMP support is disabled in default.--enable-snmp option is added
- to configure script.
- * Changes in bgpd
- ** Fix FSM bug which introduced in zebra-0.80.
- * Changes in zebra-0.80
- * access-list
- New access-list name space `ipv6 access-list' is added. At the same
- time, `access-list' statemant only accepts IPv4 prefix. Please be
- careful if you use IPv6 filtering. You will need to change your
- configuration. For IPv6 filtering please use `ipv6 access-list'.
-
- As of zebra-0.7x, user can use `access-list' for both IPv4 and IPv6
- filtering.
-
- ! zebra-0.7x
- access-list DML-net permit 203.181.89.0/24
- access-list DML-net permit 3ffe:506::0/32
- access-list DML-net deny any
- !
-
- Above configuration is not valid for zebra-08x. Please add `ipv6'
- before 'access-list' when you configure IPv6 filtering.
-
- ! zebra-0.8x
- access-list DML-net permit 203.181.89.0/24
- access-list DML-net deny any
- !
- ipv6 access-list DML-net permit 3ffe:506::0/32
- ipv6 access-list DML-net deny any
- !
- * prefix-list
- And also new prefix-list name space `ipv6 prefix-list' is added. It
- is the same as the change of `access-list'. `ip prefix-list' now only
- accept IPv4 prefix. It was source of confusion that `ip prefix-list'
- can be used both IPv4 and IPv6 filtering. Now name space is separated
- to clear the meaning of the filter.
-
- If you use `ip prefix-list' for IPv6 filtering, please change the
- stetement.
-
- ! zebra-0.7x
- ip prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
- ip prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
- ip prefix-list 6bone-filter seq 12 deny 3ffe::/16
- ip prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
- ip prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
- ip prefix-list 6bone-filter seq 30 deny any
- !
-
- Now user can explicitly configure it as IPv6 prefix-list.
-
- ! zebra-0.8x
- ipv6 prefix-list 6bone-filter seq 5 permit 3ffe::/17 le 24 ge 24
- ipv6 prefix-list 6bone-filter seq 10 permit 3ffe:8000::/17 le 28 ge 28
- ipv6 prefix-list 6bone-filter seq 12 deny 3ffe::/16
- ipv6 prefix-list 6bone-filter seq 15 permit 2000::/3 le 16 ge 16
- ipv6 prefix-list 6bone-filter seq 20 permit 2001::/16 le 35 ge 35
- ipv6 prefix-list 6bone-filter seq 30 deny any
- !
- * RIP configuration
- If you want to filter only default route (0.0.0.0/0) and permit other
- routes, it was hard to do that. Now `ip prefix-list' can be used for
- RIP route filtering.
-
- New statement:
-
- `distribute-list prefix PLIST_NAME (in|out) IFNAME'
-
- is added to ripd. So you can configure on eth0 interface accept all
- routes other than default routes.
-
- !
- router rip
- distribute-list prefix filter-default in eth0
- !
- ip prefix-list filter-default deny 0.0.0.0/0 le 0
- ip prefix-list filter-default permit any
- !
- * RIPng configuration
- Same change is done for ripngd. You can use `ipv6 prefix-list' for
- filtering.
-
- !
- router ripng
- distribute-list prefix filter-default in eth0
- !
- ipv6 prefix-list filter-default deny ::/0 le 0
- ipv6 prefix-list filter-default permit any
- !
- * BGP configuration
- So far, Multiprotocol Extensions for BGP-4 (RFC2283) configuration is
- done with traditional IPv4 peering statement like blow.
-
- !
- router bgp 7675
- neighbor 3ffe:506::1 remote-as 2500
- neighbor 3ffe:506::1 prefix-list 6bone-filter out
- !
-
- For separating configuration IPv4 and IPv6, and for retaining Cisco
- configuration compatibility, now IPv6 configuration is done by IPv6
- specific statement. IPv6 BGP configuration is done by statement which
- start from `ipv6 bgp'.
-
- !
- router bgp 7675
- !
- ipv6 bgp neighbor 3ffe:506::1 remote-as 2500
- ipv6 bgp neighbor 3ffe:506::1 prefix-list 6bone-filter out
- !
-
- At the same time some IPv6 specific commands are deleted from IPv4
- configuration.
-
- o redistribute ripng
- o redistribute ospf6
- o neighbor PEER version BGP_VERSION
- o neighbor PEER interface IFNAME
-
- Those commands are only accepted as like below.
-
- o ipv6 bgp redistribute ripng
- o ipv6 bgp redistribute ospf6
- o ipv6 bgp neighbor PEER version BGP_VERSION
- o ipv6 bgp neighbor PEER interface IFNAME
-
- And below new commands are added.
-
- o ipv6 bgp network IPV6_PREFIX
- o ipv6 bgp redistribute static
- o ipv6 bgp redistribute connected
- o ipv6 bgp neighbor PEER remote-as <1-65535> [passive]
- o ipv6 bgp neighbor PEER ebgp-multihop [TTL]
- o ipv6 bgp neighbor PEER description DESCRIPTION
- o ipv6 bgp neighbor PEER shutdown
- o ipv6 bgp neighbor PEER route-reflector-client
- o ipv6 bgp neighbor PEER update-source IFNAME
- o ipv6 bgp neighbor PEER next-hop-self
- o ipv6 bgp neighbor PEER timers holdtime <0-65535>
- o ipv6 bgp neighbor PEER timers keepalive <0-65535>
- o ipv6 bgp neighbor PEER send-community
- o ipv6 bgp neighbor PEER weight <0-65535>
- o ipv6 bgp neighbor PEER default-originate
- o ipv6 bgp neighbor PEER filter-list FILTER_LIST_NAME (in|out)
- o ipv6 bgp neighbor PEER prefix-list PREFIX_LIST_NAME (in|out)
- o ipv6 bgp neighbor PEER distribute-list AS_LIST_NAME (in|out)
- o ipv6 bgp neighbor PEER route-map ROUTE_MAP_NAME (in|out)
-
- And some utility commands are introduced.
-
- o clear ipv6 bgp [PEER]
- o show ipv6 bgp neighbors [PEER]
- o show ipv6 bgp summary
-
- I hope these changes are easy to understand for current Zebra users...
- * To restrict connection to VTY interface.
- It used to be both IPv4 and IPv6 filter can be specified with one
- access-list. Then the access-list can be appried to VTY interface
- with `access-class' stetement in `line vty' node. Below is example in
- zebra-0.7x.
-
- !
- access-list local-only permit 127.0.0.1/32
- access-list local-only permit ::1/128
- access-list local-only deny any
- !
- line vty
- access-class local-only
- !
-
- Now IPv4 and IPv6 filter have each name space. It is not possible to
- specify IPv4 and IPv6 filter with one access-list. For setting IPv6
- access-list in `line vty', `ipv6 access-class' statement is
- introduced. Let me show the configuration in zebra-0.8x.
-
- !
- access-list local-only permit 127.0.0.1/32
- access-list local-only deny any
- !
- ipv6 access-list local-only permit ::1/128
- ipv6 access-list local-only dny any
- !
- line vty
- access-class local-only
- ipv6 access-class local-only
- !
- * route-map
- New IPv6 related route-map match commands are added.
-
- o match ipv6 address
- o match ipv6 next-hop
-
- Please change your configuration if you use IP match statement for
- IPv6 route.
-
- zebra-0.7x config
- =================
- !
- access-list all permit any
- !
- route-map set-nexthop permit 10
- match ip address all
- set ipv6 next-hop global 3ffe:506::1
- set ipv6 next-hop local fe80::cbb5:591a
- !
-
- zebra-0.8x config
- =================
- !
- ipv6 access-list all permit any
- !
- route-map set-nexthop permit 10
- match ipv6 address all
- set ipv6 next-hop global 3ffe:506::1
- set ipv6 next-hop local fe80::cbb5:591a

- * zebra connection
- Protocol daemon such as ripd, bgpd, ospfd will reconnect zebra daemon
- when the connection fail. Those daemons try to connect zebra every 10
- seconds first three trial, then the interval changed to 60 seconds.
- After all, if ten connections are fail, protocol daemon give up the
- connection to the zebra daemon.
- * SNMP support (is not yet finished)
- Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
- agent. Currently lib/smux.c can be compiled only with ucd-snmp-4.0.1
- and http://ucd-snmp.ucdavis.edu/patches/012.patch. It can not be
- compiled with ucd-snmp-3.6.2.
-
- After applying the patch to ucd-snmp-4.0.1, please configure it with
- SMUX module.
-
- % configure --with-mib-modules=smux
-
- After compile & install ucd-snmp-4.0.1, you will need to configure
- smuxpeer. I'm now using below configuration.
-
- /usr/local/share/snmp/snmpd.conf
- ================================
- smuxpeer 1.3.6.1.6.3.1 test
-
- Above 1.3.6.1.6.3.1 and test is temporary configuration which is hard
- coded in lib/smux.c. Yes, I know it is bad, I'll change it ASAP.
- * HUP signal treatment

- interface.
- * Changes in zebra
- ** Installation of IPv6 route bug is fixed.
- * Changes in bgpd
- ** Very serious bug of bgp_stop () is fixed. When multiple route to
- the same destination exist, bgpd try to announce the information to
