Hi, the below is the config I am currently using, which I think is more or less the same as the one that was exposing the problem.

I can try to reproduce the issue again and get the core dump again, it’ll take me some time though.

log syslog all;
# debug protocols all;

router id 192.168.55.1;

protocol device {
}

protocol kernel kernel4 {
	ipv4 {
		export all;
	};
}

protocol kernel kernel6 {
	ipv6 {
		export all;
	};
}

protocol ospf v2 ospf4 {
	ipv4 {
	import filter {
                if ospf_router_id ~ [192.168.30.1] ||
                   ospf_router_id ~ [192.168.25.1] ||
                   ospf_router_id ~ [192.168.54.1] ||
                   ospf_router_id ~ [192.168.20.1]
                then
                   accept;
                else
                   reject;
                };
	export all;
	};

	area 0 {
		interface "br-lan" { stub; };
		#interface "vpn" { stub; };
		interface "nl" { cost 50; type ptp; authentication simple; password “xxx”;};
		interface "vpn" { cost 50; type ptp; authentication simple; password “xxx”;};
		interface "thelimes" { cost 50; type ptp; authentication simple; password “xxx”;};
	};
}


protocol ospf v3 ospf6 {
	ipv6 {
		import all;
	};

	area 0 {
		interface "br-lan" { stub; };
		#interface "vpn" { stub; };
		interface "vpn" { cost 50; type ptp; };
		interface "nl" { cost 50; type ptp; };
		interface "thelimes" { cost 50; type ptp; };
	};
}
