Hello.
I need to announce one autonomous system from under another so that the
path "world -> AS65007 -> AS65065" must be visible from the outside world.
I successfully do it on version 1.6.6 (config-file and 'show route' from
live system with changed ip-addresses in attach).
Exactly the same method does not work on version 2.0.12 - for unknown
reason I get ALL imported from second AS static routes in the unreachable
state (bird-2.0.12-config with 'show route' at the end of file).
Has something changed in the work process of the bird, or am I doing
something wrong?
bird 1.6.6 on debian 10 / kernel 4.19.181
bird 2.0.12 on debian 11 / kernel 5.10.179
Peering interfaces on both systems are created as follows:
