Description
Use ignore-first-as to configure BGP to ignore the first AS number of EBGP route updates.
Use undo ignore-first-as to configure BGP to check the first AS number of EBGP route updates.
By default, BGP checks the first AS number of a received EBGP route update. If the first AS number is not
that of the BGP peer, the BGP router discards the route update.
