Hello,
I only want to say I managed to make it work.
I am using OSPF with type nonbroadcast and each "legal" neighbor is
stated in neighbor list.
In this setup new neighbor started to "work" when I added it to majority
of neighbors. Previously I tested it with 3 neighbors and those "old
neighborhood" probably voted my new peer out (sorry for not-so-precise
terms). When I got majority, everyting started to work as expected.

Hello,
I have 10 routers talking OSPF on a switch on network 10.10.4.0/24. Now
I want to add 11th and am unable to make it work. I see the new router
in neighbors, also other neighbors on the new router. The new router
doesn't get any routes from others, because others see it as unreachable
(10.10.4.45 is the new router, 10.10.4.48 is one of old working routers):
bird> show ospf topology all
...
router 10.10.4.45
unreachable
network 10.10.4.0/24 metric 10
router 10.10.4.48
distance 10
network 10.8.253.0/26 metric 50
network 10.10.4.0/24 metric 10
...
On the new router - all old routers are unreachable:
bird> show ospf topology all
...
router 10.10.4.45
distance 0
network 10.10.4.0/24 metric 10
router 10.10.4.48
unreachable
network 10.8.253.0/26 metric 50
network 10.10.4.0/24 metric 10
...
The normal traffic (ping, ssh) works of course, IP configuration is
currently at minimum (single interface, IP 10.10.4.45/24). OS is Linux
5.10, bird 2.0.7.
Thanks for any help with this.
