My understanding is that there are sync problems with deploying mcast native. Most notedly when BGP uses memory and cpu and then pruning/mrouting also wishes to use the cpu. I haven't personally experimented with this, but have heard interesting stories about egress problems near borders. _J Robert Laughlin said:
I am also considering enabling multicast routing, I would appreciate hearing more about this as well.

OK, I'll take a stab at it, although it'll be in the form of a technical question, which will hopefully draw technical content/answers.
I'm getting ready to run some native multicast on our backbone, mainly as an experiment in replacing our existing set of DVRMP/MRouted tunnels.
Equipment is cisco 7XXX and 4500, with a 2501 CPE router (my home connection). Most are running some flavor of 11.2, with one or two still running 11.1.
I'm looking for tips and suggestions from folks who are actually running native multicast in a cisco environment.
While I've been getting help from Dave Meyer (Thanks, Dave!), I figure that others could benefit from the same information, hence my posting here.
