Thanks guys. You both offered awsome info.
Take heed group, I have pasted both Brian and Bernards posts into this
message for others convenience.
Well, dense mode is too easy so you can probably scratch that. Sparse-dense
with auto-rp would be likely I would think. rp filtering, group filtering,
load-balancing over equal cost paths (can be tricky). Make sure you
understand RPF checks and how to use static mroutes. It's important to
understand static mroutes aren't like regular static routes, they don't
alter the path multicast traffic take, they only modify the rpf interface
(the interface you expect it to come in on).
There a command a lot of people don't know is available: show tech
ipmulticast, which gives you virtually everything you need to troubleshoot
multicast.
There should be some good links on multicast on CCO. I would also invest in
Beau Williamson's book "Developing IP Multicast Networks" (Cisco Press).
Let's just say every member on the routing protocol team in RTP has a copy
of it, it's the Bible.

The last link is probably the place to start, as well as the
ftpeng.cisco.com sites.
