Views BGP view, BGP-VPN instance view Predefined user roles network-admin Parameters group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer group must have been created. ip-address: Specifies a peer by its IP address. The peer must have been created. ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created. as-number: Specifies a fake AS number in the range of 1 to 4294967295. Usage guidelines After you move a BGP router from an AS to another AS (from AS 2 to AS 3 for example), you have to modify the AS number of the router on all its EBGP peers. To avoid such modifications, you can configure the router to advertise a fake AS number 2 to its EBGP peers so that the EBGP peers still think that Router A is in AS 2. The peer fake-as command is only applicable to EBGP peers or peer groups. If you execute the peer fake-as command on the local router, specify the local router's AS number on the peer as the fake local AS number specified in the command. 283
