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. To view the failed enforce-
first-as check counter, use the
show ip bgp ipv6 unicast neighbors
command.
If you disable
enforce-first-as
, view it using the
show ip protocols
command.
