Hi!
Is there any reason why broadcast and multicast RIP can't be run on the same interface? I haven't read the RFCs, but we'd only be using
I did not see why its usefull so I just did not allow it..
this in a student lab setting with the multicast interface in mode "quiet", so I think it should be okay. Here's a patch to bird-1.0.5 to allow this:
Looks okay to me. (Please, diff -u next time.) mj, I no longer have checked-out bird (low on disk space, etc.), can you please apply it? Pavel
