Usage
Information
This is enabled by default; that is, for all updates received from EBGP peers, BGP ensures that
the first AS of the first AS segment is always the AS of the peer. If not, the update is dropped
and a counter is incremented. Use the show ip bgp ipv6 unicast neighbors
command to view the failed enforce-first-as check counter.
If you disable enforce-first-as, it can be viewed using the show ip protocols
command.
