| |
| * Changes in Quagga [] |
| |
| - [zebra] "no link-detect" is no longer the default. |
| |
| The previous release of Quagga always explicitly writes-out the |
| link-detect configuration state. Therefore, to retain current behavior |
| save your config with the prior release before updating. |
| |
| Otherwise, review your configuration. Note, most users will generally |
| want to have link-detect enabled, and so can just remove 'no |
| link-detect' from their interface configuration. |
| |
| This release also adds a global configuration to specify the default, |
| which can be specified in the zebra configuration as: |
| |
| default link-detect (on|off) |
| |
| This will then apply to any interface which does not have link-detect |
| explicitly configured. |
| |
| * Changes in Quagga 0.99.24 |
| |
| User-visible changes: |
| - [pimd] New daemon: pimd provides IPv4 PIM-SSM multicast routing. |
| - [bgpd] New feature: "next-hop-self all" to override nexthop on iBGP route |
| reflector setups. |
| - [bgpd] route-maps have a new action "set ipv6 next-hop peer-address" |
| - [bgpd] route-maps have a new action "set as-path prepend last-as" |
| - [bgpd] Update validity checking (particularly MP-BGP / IPv6 routes) was |
| touched up significantly. Please report possible bugs. |
| - [ripd] New feature: RIP for IPv4 now supports equal-cost multipath (ECMP) |
| - [zebra] Multicast RIB support has been extended. It still is IPv4 only. |
| - [zebra] "no link-detect" is now printed in configurations since it won't |
| be the default anymore soon. To retain current behaviour, re-save your |
| configuration after updating to 0.99.24. |
| |
| Distributor-visible changes: |
| - --enable-pimd is added to enable pimd. It is considered experimental, though |
| unless the distribution target is embedded systems with little flash, there |
| is no reason to not include it in packages. |
| - --disable-ipv6 no longer exists as an option. It's 2015, your C library |
| really needs to have IPv6 support by now. |
| - --disable-netlink no longer exists as an option. It didn't work anyway. |
| - --disable-solaris no longer exists as an option. It only controlled some |
| init scripts. |
| - --enable-isisd is now the default. |
| - mrlg.cgi is no longer included (it was severely outdated). It can be found |
| independently at http://mrlg.op-sec.us/ |
| - build on Linux with the musl C library should now work |
| |
| * Changes in Quagga 0.99.23 |
| |
| Known issues: |
| - [bgpd] setting an extcommunity in a route map on a route that already has |
| an extcommunity attribute will cause bgpd to crash. This issue will be |
| fixed in a followup minor release. |
| |
| User-visible changes: |
| - [lib] Performance enhancements on hashes and timers. |
| - [bgpd] New feature: iBGP TTL security. |
| - [bgpd] New feature: relaxed bestpath criteria for multipath and improved |
| display of multipath routes in "show ip bgp". Scripts parsing this output |
| may need to be updated. |
| - [bgpd] Multiprotocol peerings over IPv6 now try to find a more appropriate |
| IPv4 nexthop by looking at the interface. |
| - [ospf6d] A large amount of changes has been merged for ospf6d. Careful |
| evaluation prior to deployment is recommended. |
| - [zebra] Recursive route support has been overhauled. Scripts parsing |
| "show ip route" output may need adaptation. |
| - [zebra] IPv6 address management has been improved regarding tentative |
| addresses. This is visible in that a freshly configured address will not |
| immediately be marked as usable. |
| - [*] a lot of bugs have been fixed, please refer to the git log |
| |
| * Changes in Quagga 0.99.22 |
| |
| - [bgpd] The semantics of default-originate route-map have changed. |
| The route-map is now used to advertise the default route conditionally. |
| The old behaviour which allowed to set attributes on the originated |
| default route is no longer supported. |
| - [bgpd] There is now a replace-as option to neighbor ... local-as ... |
| no-prepend. For details, refer to the user documentation. |
| - [zebra] An FPM interface has been added. This provides an alternate |
| interface to routing information and is geared at OpenFlow & co. |
| - [snmp] AgentX is now supported; the old smux backend is considered |
| deprecated. ospf6d has also had OSPFV3-MIB added. |
| - [*] several issues with configuration save/load/apply have been fixed, |
| in particular on ospf "max-metric router-lsa administrative" and |
| "distribute-list", bgpd "no neighbor activate", isisd "metric-style", |
| - [*] a lot of bugs have been fixed, please refer to the git log |
| |
| * Changes in Quagga 0.99.21 |
| |
| - [bgpd] BGP multipath support has been merged |
| - [bgpd] SAFI (Multicast topology) support has been extended to propagate |
| the topology to zebra. |
| - [bgpd] AS path limit functionality has been removed |
| - [babeld] a new routing daemon implementing the BABEL ad-hoc mesh routing |
| protocol has been merged. |
| - [isisd] a major overhaul has been picked up. Please note that isisd is |
| STILL NOT SUITABLE FOR PRODUCTION USE. |
| - [*] a lot of bugs have been fixed, please refer to the git log |
| |
| * Changes in Quagga 0.99.10 |
| |
| - [bgpd] 4-byte AS support added |
| - [bgpd] MRT format changes to version 2. Those relying on |
| bgpd MRT table dumps may need to update their tools. |
| - [bgpd] Added new route-map set statement: "as-path exclude" |
| - Zebra RIB updates queue has evolved into a multi-level |
| structure to address RIB consistency issues. |
| |
| * Changes in Quagga 0.99.2 |
| |
| - [bgpd] Work queues added to bgpd to split up update processing, |
| particularly beneficial when a peer session goes down. AS_PATH |
| parsing rewritten to be clearer, more robust and ready for 4-byte. |
| |
| - [ripd] Simple authentication is no longer the default authentication |
| mode for ripd. The default is now no-authentication. Any setups which |
| used simple authentication will probably need to update their |
| configuration manually. |
| |
| - [ospfd] 1s dead-interval with sub-second Hellos feature added. |
| SPF timers now specified in milliseconds, and with adaptive |
| hold-time support. RFC3137 Stub-router support added. Default ABR |
| type is now 'cisco'. |
| |
| - Solaris least privileges support added. |
| |
| * Changes in Quagga 0.99.1 |
| |
| - Zserv is now buffered via threads and non-blocking in most cases for both |
| clients and zebra, which should improve responsiveness of daemons when |
| they must send many messages to zebra. |
| |
| - 'show thread cpu' now displays both cpu+system and wall-clock time, |
| where getrusage() is available. |
| |
| - Background threads added and workqueue API added, with a |
| 'show work-queues' command. Thread scheduling improved slightly. |
| |
| - Zebra now has a work-queue for RIB processing. See 'show work-queues' in |
| the zebra daemon vty. |
| |
| - Support for interface renaming on Linux netlink systems. |
| |
| - GNU Zebra bgpd merges, including BGP Graceful-restart and "match ip |
| route-source" command. |
| |
| - Automatic logging of backtraces should daemons crash to assist in |
| diagnosis. See the documentation for more information on configuring |
| logging correctly, and set --enable-gcc-rdynamic if compiling with gcc. |
| |
| * Changes in Quagga 0.98.0 |
| |
| - Logging facilities upgraded. One can now specify a severity level |
| for each logging destination. And a new "show logging" command gives |
| thorough information on the current logging system configuration. |
| |
| - Watchquagga daemon added. This is not well tested yet. Please try |
| monitor mode first before enabling restart features. It is important |
| to make sure that the various timers are configured with appropriate |
| values for your site. |
| |
| - BGP route-server support added. See the texinfo documentation. |
| |
| - OSPF API initialisation is disabled by default even if compiled in. You |
| can enable it with -a/--apiserver command line switch. |
| |
| - "write-config integrated" vtysh command replaced with "service |
| integrated-vtysh-config" command. |
| |
| - Router id is now handled by zebra daemon and all daemons receive changes |
| from it. Router id can be overriden in daemons' configurations of course. |
| To fix common router id in zebra daemon you can either install non-127 |
| address on loopback or use "router-id x.x.x.x" command. |
| |
| - "secondary" keyword is removed from ip address configuration. All |
| supported OS'es have their own vision what's secondary address and |
| how to handle it. |
| |
| - Zebra no longer enables forwarding by default. If you rely on zebra to |
| enable forwarding make sure to add '<ip|ip6> forwarding' statements |
| to your zebra configuration file. |
| |
| - All libraries are built and used shared, on platforms where libtool |
| supports shared libraries. |
| |
| - Router advertisement syntax is changed. In usual cases (if you didn't do |
| any fancy stuff) it's enough to change lines in configuration from: |
| "ipv6 nd prefix-advertisement X:X:X:X::/X 2592000 604800 autoconfig on-link" |
| to: |
| "ipv6 nd prefix X:X:X:X::/X" |
| |
| All router advertisement options are documented in texi documentation. |
| |
| - --enable-nssa configure switch is removed. NSSA support is stable enough. |
| |
| - Daemons don't look at current directory for config file any more. |
| |
| * Changes in Quagga 0.96.5 |
| |
| - include files are installed in $(prefix)/include/quagga. Programs |
| building against these includes should -I$(prefix)/include and e.g. |
| #include <quagga/routemap.h> |
| |
| - New option --enable-exampledir puts example files in a separate |
| directory from $(sysconfdir), easing NetBSD pkgsrc hierarchy rules |
| compliance. |
| |
| - New configure options --enable-configfile-mask and |
| --enable-logfile-mask to set umask values for config and log |
| values. Masks default to 0600, matching previous behavior. |
| |
| - Import current CVS isisd from SourceForge, then merge it with |
| the Quagga's Framework. |
| |
| * Changes in Quagga 0.96.4 |
| |
| - Further fixes to ospfd, some relating to the PtP revert. Interface |
| lookups should be a lot more robust now. |
| |
| - Fix for a remote triggerable crash in vty layer. |
| |
| - Improvements to ripd, and addition of split horizon support. |
| |
| - Improved bgpd table support, now dumps at time of day intervals rather |
| than time from startup intervals. Much improved support for IPv6 table |
| dumps. show commands for views improved. |
| |
| * Changes in Quagga 0.96.3 |
| |
| - revert the 'generic PtP' patch. Means Quagga will no longer work with |
| FreeSWAN, however, on the plus side this gets rid of a lot of niggly bugs |
| which the PtP patch introduced. |
| |
| * Changes in Quagga 0.96.2 |
| |
| - Fix crash in ospfd |
| |
| * Changes in Quagga 0.96.1 |
| |
| - Iron out problem with the privileges definitions |
| |
| * Changes in Quagga 0.96 |
| |
| - Privilege support, daemons now run with the minimal privileges needed, see |
| the documentation for details. |
| |
| - NSSA ABR support in ospfd. |
| |
| - OSPF-API support merged in. |
| |
| - 6WIND patch merged in. |

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

| becomes default. So both options are removed from configure.in. To |
| revert old behavior please specify below option. |
| |
| --enable-tcp-zebra # TCP/IP socket is used for protocol daemon and zebra. |
| --enable-oldrib # Turn on old RIB implementation. |
| |
| Old RIB implementation will be removed in zebra-0.91. |
| |
| ** From this beta release --enable-multipath is supported. This |
| option is only effective on GNU/Linux kernel with |
| CONFIG_IP_ADVANCED_ROUTER and CONFIG_IP_ROUTE_MULTIPATH is set. |
| |
| --enable-multipath=ARG # ARG must be digit. When ARG is 0 unlimit multipath number. |

| |
| ** Metric value is reflected to kernel routing table. |
| |
| ** "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 |
| route-refresh". |
| |
| * Changes in ripd |
| |
| ** Change "match ip next-hop" argument from IP address to access-list |
| 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. |
| |

| |
| ** 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 |

| |
| ** 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 |

| |
| * 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 |
| |
| From zebra-0.80, ripd will reload it's configuration file when ripd |
| receives HUP signal. Other daemon such as bgpd, ospfd will support |
| HUP signal treatment soon. |
| |
| * Changes in zebra-0.79 |
