Hello...
I think that I need to work with multicast, to enable RIP (qaugga) and a
speedtouch router, but I dont' t understand why is MULTICAST enable on
interfaces and netstat -g don't show them.
The speedtouch receives the routes from netbsd, but the routes from the
speedtouth don't.
# netstat -gn
Virtual Interface Table is empty
Multicast Forwarding Cache is empty

I think that a route like 224.0.0.9 should exist, but I' really don't
understand Multicast
Also my gre tunnel don't work, but I think it's a limitation from my
speedtouth router, but gif tunnel work well.
Can some one give me any direction on multicast.
Thanks
