You will need to verify you are receiving 2 default routes on your routers form AS 1213, to ensure connectivity: sh ip bgp 0.0.0.0 [Cisco] show route protocol bgp 0.0.0.0/0 [JunOS] $user@$router> sh ip bgp 0.0.0.0 BGP routing table entry for 0.0.0.0/0 Paths: 2 available 1213 193.1.9.197 from 193.1.9.197 (193.1.9.197) Origin IGP, metric 5, localpref 100, IGP metric 1, weight 0, received 3d12h ago, valid, internal, best 1213 87.44.56.113 from 87.44.56.113 (87.44.48.36) Origin IGP, metric 10, localpref 100, IGP metric 1, weight 0, received 3d12h ago, valid, external The metric of 5 and 10 are important.
