Again we get problems with multicast (all aour routers stop sending igmp last night). So I must ask that what kind possibility is get that real broadcast feature to bird? It solve many problem when you have dozens of routers and links where you cannot guarantee that multicast work properly. On this case naturally right method is reboot all routers and fix that igmp. BUT on first place that multicast is mostly pain in the ass all time when you do not have full control to whole network so I prefer choice that we can get rid off that.
So I humbly asking new feature. It is real broadcast type. Because of compatibility reasons it is unpossible use type bcast for that and rename multicast for type mcast I suggest that new type is rbcast. It is extension over rfc but it is really usefull one. On real broadcast packets send to 255.255.255.255 so they does not get meshed up with multicast specific rules.
Implemented in commit 95127cbbb76e8870e029454a5313bc4b6ce69a4a. Option 'real broadcast', relevant for 'type broadcast' and 'type ptp'. Uses directed broadcast addresses instead of 255.255.255.255, but it is the same on ethernet link-layer (ff:ff:ff:ff:ff:ff). -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
