Yes, but I was just testing it and don't have the commands
I used now. I think I had to use 'ifconfig cipcb0 multicast'
before it would work, and I didn't use mrouted, I used smcroute
to set up a static route.
My peer was a Cisco router running PIM so I ended up configuring
a GRE tunnel on the Linux endpoint with the route traversing the
CIPE tunnel. The other GRE endpoint was directly on the Cisco
and again I used PIM/smcroute on the Linux side. I did make
a note of those commands if you want to try it that way. I set
this up expecting to tunnel data to a remote office over the internet
for a few days while a frame relay connection was reconfigured but
it worked so well that I didn't switch to the frame connection for
