Peer group config. in a Route reflector

Post by Guest » Mon Dec 22, 2008 2:53 am

Dears , Im trying to configure peer group in one of my PE router which is working as a route reflector  I applied the below config. Now I want to bring the IP 172.16.14.2 and 172.16.14.3 as route reflector clients ,but Im getting below error (config-router-af)#neighbor 172.16.12.2 route-reflector-client% Invalid command for a peer-group member router bgp 65000bgp log-neighbor-changesneighbor internal peer-groupneighbor internal remote-as 65000neighbor internal update-source Loopback1neighbor 172.16.14.2 peer-group internalneighbor 172.16.14.3 peer-group internal address-family vpnv4neighbor internal send-community extendedneighbor 172.14.14.2 activateneighbor 172.14.14.3 activate Before applying peer-group config ,my config. was as given below .Also whether the config. "neighbor 172.14.14.2 activate" is needed under vpnv4 ? .If i remove this neighbor going down and at the same time I can put something like ""neighbor internal activate"address-family vpnv4neighbor 172.16.14.2 route-reflector-clientneighbor 172.16.14.2 send-community extendedneighbor 172.16.14.2 activate I will rate the helpful inputs RegardsHari

Hari, Here are some sample configs, this should be what you
e after: RR Configs: router bgp 65000 bgp log-neighbor-changes neighbor internal peer-group neighbor internal remote-as 65000 neighbor internal update-source Loopback1 neighbor 172.16.14.2 peer-group internal neighbor 172.16.14.3 peer-group internal ! address-family ipv4  neighbor internal send-community both  neighbor internal route-reflector-client  neighbor internal next-hop-self  neighbor 172.14.14.2 activate  neighbor 172.14.14.3 activate  no auto-summary  no synchronization exit-address-family ! address-family vpnv4  neighbor internal send-community both  neighbor internal route-reflector-client  neighbor internal next-hop-self  neighbor 172.14.14.2 activate  neighbor 172.14.14.3 activate exit-address-family! RRC Configs: router bgp 65000 bgp log-neighbor-changes neighbor Route_Reflector peer-group neighbor Route_Reflector remote-as 65000 neighbor Route_Reflector update-source Loopback0 neighbor 172.14.14.1 remote-as 65000 neighbor 172.14.14.1  peer-group RouteReflectorPG ! address-family ipv4  no synchronization  neighbor Route_Reflector send-community both  neighbor Route_Reflector next-hop-self  neighbor 172.14.14.1 activate  no auto-summary exit-address-family ! address-family vpnv4  neighbor Route_Reflector send-community both  neighbor Route_Reflector next-hop-self  neighbor 172.14.14.1 activate exit-address-family ! Here are the references on CCO (formerly UniverCD): Assigning Clients to a Peer Group: http://www.cisco.com/en/US/docs/ios/ipr ... #wp1015335 Creating a Peer Group:http://www.cisco.com/en/US/docs/ios/ipr ... #wp1015489 http://www.cisco.com/en/US/docs/ios/ipr ... #wp1056201 As you can see, all the answers are a search away!  HTH Joe.

Dear Joe , Thanks for the config. I done the same thing .and its working. Also in my case all my peer-group membors should be in vpnv4 addressfamily. ,so i wish to configure like "neigh internal   activate" under vpn4 . Is it possible ? Or  whether i need to type "neighbor x.x.x.x activate for all membors ?  .  regards

Hi Hari, You need to specifiy the neighbor by IP to activate. As per basic Peer-Group configurations, the use of the peer groups make its more efficient and easier to maintain any BGP attibute manipulation of multiple neighbors to just the one peer-group command, so all you have to do is activate that neighbor under the AF for it to take part in that peer-group and what is configured for that peer-group to do. Thanks, Joe.
