Hi, I'm setting up bird6 as core IPv6 BGP router and in order to annunce my subnet aggregated i used the blackhole method: protocol static { route 2a01:9c01::/32 drop; } but when i started bird i keep getting this error: bird6: device1: Scanning interfaces bird6: kernel1: Scanning routing table bird6: kernel1: Pruning table master bird6: kernel1: 2a01:9c01::/32: reinstalling bird6: Netlink: No such device bird6: kernel1: Pruning inherited routes it seems that linux doesn't allow to set blackhole ipv6 routes without specifing the device: root@:~# ip -f inet6 route add blackhole 2a01:9c01::/32 RTNETLINK answers: No such device if I append dev lo the route inserts without problems. This error does not happen with reject and so protocol static { route 2a01:9c01::/32 reject; } works like a charm. There is a way to solve this issue? Or maybe you can consider allowing to specify device in route drop command. Regards. G.Ravasio
