Issues running BMP protocol in v3.0.1

[admin at nxthdr.dev]

Hey,

I've migrated from 2.16.1 to 3.0.1 and I'm facing some issues with the BMP protocol.
The TCP session goes up but I don't receive all peers up notifications. I receive some (but not all it seems) when I restart bird after have started my BMP collector. If I do the opposite, I get none.

Also, I don't receive route monitoring messages. To be precise, I receive only one route monitoring message when I receive a peer up notification. But this one is empty (meaning no announced/withdrawn prefixes in it). Also I receive it just just before the peer up, which is a bit weird. I should receive a tons of them, with announced prefixes in it, right after the peer up.

Here is my BMP configuration:

protocol bmp {
station address ip 2a06:de00:50:cafe:100::c port 4000;
monitoring rib in pre_policy;
monitoring rib in post_policy;}

bird> show protocols all bmp1
Name Proto Table State Since Info
bmp1 BMP --- up 18:08:26.528 Established
Created: 18:08:16.105
Station address: 2a06:de00:50:cafe:100::c
Station port: 4000
Pending TX: 0 B (limit 1024.0 MB)
Session TX: 789 B Total TX: 789 B

Do you experience the same behavior?

Please let me know if you need more information, I'm happy to make some other tests if needed.

Best,Matthieu.
