Re: bird 2.0.7 crashes with OSPF

22 Dec 2019

      Hi,

I didn’t specified the instance id in my config and I use v2 for IPv4.
It’s working for me. Here is my config:

protocol ospf ospf_ipv4 {
        ipv4 {
                import all;
                import keep filtered;
                import limit 200 action block;
                import filter {
                        if (net ~ [ 0.0.0.0/0 ]) then {
                                reject;
                        }
                        else {
                                accept;
                        }
                };

                export filter {
                        if (proto = "kernel_ipv4" || proto = "direct1") then {
                                accept;
                        }
                        else reject;
                };
        };

        area 0.0.0.0 {
                interface "tinc0" {
                        bfd;
                };
        };
};

protocol ospf v3 ospf_ipv6 {
        ipv6 {
                import all;
                import keep filtered;
                import limit 200 action block;
                import filter {
                        accept;
                };

                export filter {
                        if (proto = "kernel_ipv6" || proto = "direct1") then {
                                accept;
                        }
                        else reject;
                };
        };

        area 0.0.0.0 {
                interface "tinc0" {
                        bfd;
                };
        };
};
