Support “redistribute dhcp” for IS-IS Agent (IPv6)

Description EOS 4.23.0F adds support for redistributing DHCPv6 routes in IS-IS when using the multi-agent routing protocol mode. Support for this feature in single agent mode has existed since EOS 4.21.0 Configuration DHCPv6 routes can be redistributed into IS-IS via following CLI in only IPv6 address-family mode. Arista(config)#router isis A Arista(config-router-isis)#address-family ipv6 Arista(config-router-isis-af)#redistribute dhcp Show Commands DHCPv6 routes redistributed into IS-IS can be seen in show isis database detail show command # show isis database detail IS-IS Instance: inst1 VRF: default IS-IS Level 1 Link State Database LSPID Seq Num Cksum Life IS Flags 1111.1111.1001.00-00 10 19778 1101 L1 <>...

Supporting ‘match ip next-hop’ clause for static routes redistributed into IGPs

Description EOS 4.23.0F adds support for ‘match ip next-hop’ clause for static routes redistributed into IGPs. There was already support for this feature in single agent mode. EOS 4.23.0F adds support for multi-agent mode as well. We can apply ‘match ip next-hop’ route-map clause while redistributing static routes into IGPs to redistribute the static routes whose configured next-hops satisfies the route-map policy. Configuration To configure a static route (config)#ip route 10.20.30.0/24 1.2.3.4 To configure a prefix-list (config)#ip prefix-list prefixListName (config-ip-pfx)#permit 1.2.3.4/32 Here 1.2.3.4 is a configured next-hop for static route 10.20.30.0/24 To configure a route-map (config)#route-map routeMapName (config-route-map-routeMapName)#match ip next-hop...

Disabling the IS-IS authentication check on the receive side

Description EOS 4.22.1F adds support for disabling the IS-IS authentication check for received IS-IS PDUs. By enabling this feature on a node, the IS-IS authentication check for all of the received IS-IS PDUs on that node will be skipped. Configuration We have added an optional ‘rx-disabled’ token to our existing configuration for IS-IS authentication. Configuring ‘rx-disabled’ for an IS-IS instance causes LSPs, PSNPs and CSNPs to skip the IS-IS authentication check.  The updated syntax for configuring authentication for an IS-IS instance is now: [no] authentication mode <text|md5|(sha key-id <id>)> [rx-disabled] [level-1|level-2] An example configuration (config)# router isis 1 (config-router-isis)# authentication...
