BIRD ignored routes

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
