[OSPF] BIRD <> Mikrotik

RouterOS Forwarding Protocols
1

I’m trying to bind bird with ospf mikrotik and BIRD. Once i managed it to run, but after i’ve restarted the bird instace, the same problem appeared.

bird.conf:

protocol ospf LandtechOSPF {
       tick 2;
        rfc1583compat yes;
        area 0.0.0.0 {
                stub no;
                interface "eth1" {
                        hello 10;
                        retransmit 5;
                        cost 10;
                        transmit delay 5;
                        dead 40;
                        dead count 40;
                        wait 50;
                        type broadcast;
                };
        };
}

Big thanks for help!

From BIRD manual

The RFC says that a router should check the checksum of every LSA to detect hardware problems. BIRD does not do this to minimalize CPU utilization.

It looks like packets with wrong checksum is sent from BIRD because there is no checksum comparison in BIRD.

Is there any way do disable the cheksum check on the Mikrotik?
