Usage Information When you enable failover, BGP keeps track of IP or IPv6 ability to reach the peer remote address and the peer 
local address. Whenever either address becomes unreachable (for example, no active route exists in the routing 
table for the peer IP or IPv6 destination/local address), BGP brings down the session with the peer.
Related Commands
• show ip bgp neighbors — display information on the BGP neighbors.
neighbor local-as
To accept external routes from neighbors with a local AS number in the AS number path, configure Internal BGP (IBGP) routers.
Syntax
neighbor {ip-address | peer-group-name} local-as as-number [no-prepend]
To return to the default value, use the no neighbor {ip-address | peer-group-name} local-as 
command.
Parameters
ip-address Enter the IP address of the neighbor in dotted decimal format.
peer-group-name Enter the name of the peer group to set the advertisement interval for all routers in the 
peer group.
as-number Enter the AS number to reset all neighbors belonging to that AS. The range is from 0 to 
65535 (2 byte), from 1 to 4294967295 (4 byte) or from 0.1 to 65535.65535 (dotted 
format).
