Hmm, I did a quick tcpdump the day before but didn't spot any withdrawals. Today, however , I do see both routes being accepted. The only difference between before and now is that the next-hop is no longer the same as the IP of the session where this was learned.

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.
Hi
First thing to try would be to run just one Exabgp link, with disabled add-path, to see if something changes. Another good idea would be to try to catch the [3] with tcpdump, as the receiver (AS_Z) not only ignore these updates, but also consider them to be withdraws.
