Hi Users of BIRD!
I have only heard about "OSPF Unnumbered" a couple of times, and never
have seen any clear explanation or specific details. And based on that,
I had the false assumption that "unnumbered" would imply "having no
address on the interfaces"; maybe only an IPv4 address used as

Ahoj Ondrej,
Thanks for your feedback. Finally I resolved it, it was firewall issue
locally on some defined bfd sessions; thus the Socket errors..
The thing is that last evening we had a flap on BFD sessions for no
apparent reason at only 3 BGP peers , on our 2 different Route Servers.

Not exactly. Yes, the session is handled by the kernel. But it should
be possible to set the TTL before listening to the socket. Looks like
bird just do not use the TTL for the listening BGP sessions before it
gets incoming connection. And it somewhat OK for the case when bird
listens a single

The question raised by colleague Irene reminded me of a topic that may or
may not be the focus of BIRD's development.
I imagine that the biggest supporters of SMP/Multi-Core/Thread-Safe
evolution on BIRD are Operators of Route-Servers of large IXPs, and
operators of large-scale Route-Reflectors.
The setup of the TCP session is handled by the kernel, hence the higher
TTL. Once TCP is established, (e)BGP tends to use a TTL of 1 unless it's a
multihop session.l, or you're using GTSM.
It's expected, and is partly due to the limitations of how sockets are
implemented in Linux.

Hello dear community,
I would like to pose a question regarding the error I receive concerning
BFD : socket operation not permitted.
The bfd is configured with multiplier 3; interval 300ms; idle tx
interval 1 sec;
Thanks a lot for your feedback in advance!
