OSPF over OpenVPN

[Charles van Niman]

Hello,

     Based on the output you provided, it appears BIRD/OSPF is not seeing
your interfaces? In BIRD CLI, if you compare "show interfaces" with "show
ospf interfaces" do you see any difference? I am using a very basic config
(only defining cost) for each OpenVPN tun interface I am using, and its
working over here.

bird.conf:

protocol ospf SlothNet {
  rfc1583compat yes;
  area 0.0.0.0 {
    networks {
      172.22.150.64/26;
      172.23.158.64/26;
    };
    stub no;
    interface "tun-node43" {
        cost 20;
    };
    interface "tun-node69" {
        cost 180;
    };
    interface "tun-node96" {
        cost 70;
    };
    interface "tun-node28" {
        cost 130;
    };
    interface "eth1" {
        cost 10;
    };
    interface "lo" {
        stub;
    };
  };
}

bird output:
