Could you try add 'passive' to the working example to see whether the issue is related to one-way establishment, or neighbor-range mode?
yes, adding 'passive' to the working example keeps it still working.
Also, do you have any messages in logs related to that (esp. if you enable debug logging)?
Not really. Having... log syslog all; debug protocols all; ...on both, r1 and r2, leads on r2 to: bird[18503]: Started bird[18503]: r1: Started bird[18503]: r1: Connect delayed by 5 bird[18503]: r1: Connecting to 2001:db8:1::1 from local address :: On r1, there is nothing related to r2, while I am seeing via tcpdump inbound BGP connections from r2 (being unanswered). However, running "telnet r1 179" from r2 leads at least to a BGP protocol related reply (within the telnet connection) from r1. Regards, Robert
