Thanks for the info -

We are trying to do exactly what you said won't work - Getting multicast to
work for a number of Linux Servers running as VM guests using CTC's back to
TCPIP ... We figured if we could connect a single Linux server to the an OSA
card (we only have a gigabit card available) we could then attach all the
servers we wanted in the multicast group via VCTC to it.

The standard mrouted works OK if you have a directly attached non-shared
NON-QDIO OSA (so you can't use the gig Ethernet OSA at all) or the CLAW
driver as I modified it a few months ago and the latest IOS code with fixes
for intra-CIP multicast/broadcast/directed unicast forwarding. It doesn't
work well at all with IUCV or CTC links, so you may have some difficulty
getting traffic to flow properly.

Are you expecting PIM or DVMRP traffic? If you can, try configuring for
DVMRP and using tunneling to get the mcast packets into the box, and then do
mcast routing from there. Distributing mcast inside the box isn't really
useful at the moment (until guest LANs support mcast and broadcast) and is
REALLY cycle-intensive -- can you share what you're looking to use mcast
for?
