Hi All, I’m having an issue with bird ignoring some prefixes it’s receiving. I'm new to bird and may be overlooking something simple. The config is essentially this
[1] Exabpg1:AS_X < — > BIRD:AS_Y (route-server) [2] Exabgp2:AS_X < — > BIRD:AS_Y (route-server) [3] BIRD:AS_Y < — > BIRD:AS_Z [1] & [2] behave as expected, however when the route-server exports to the 2nd BIRD instance the routes are ignored. The debug file unfortunately makes no mention of the routes being ignored. Any suggestions on how I can find the cause for those being ignored. Attached are the configs and outputs from BIRD Thanks -nat
