Hello everyone, I’m having an issue with FRR running on Cumulus (4.0+cl3u10), which is peering BGP to BIRD (2.0.2, also tried 1.6.3). When certain routes from FRR are advertised to BIRD (I configured them through vrf leaking on FRR, but not sure if that matters, or its just something with the routes), BIRD terminates the BGP session with an `Optional attribute error` (on BIRD 2.0.2, different error on 1.6.3) when receiving the BGP UPDATE message. I’m not sure if this an FRR or BIRD issue, so I'm hoping someone here could take a look if the UPDATE message from FRR could possibly be malformed, or is BIRD handling this in an odd way. I've attached the tcpdump as well as error logs from BIRD, along with the bird.conf, as well a portion of the FRR config. 100.91.38.1 is the host running BIRD. 100.91.38.61 is the host running FRR. Regards, Derrick
