Most probably not. Since your nexthop is not valid the routes are not valid. Next step is 'bgpctl show fib $peerfibn1' and make sure it returns a valid and hopefully the correct route. I have the feeling that $peerfibn1 is resolved via the default route and therefor not considered for validating the neighbor. Also do a 'route -nv get $peerfibn1' and compare with the fib output. -- :wq Claudio > 2015-05-10 14:37 GMT-04:00 Henning Brauer <[email protected]>: > > > * Michel Blais <[email protected]> [2015-05-07 17:59]: > > > I have 2 BGP peer from different provider (AS5769 and AS22652).
