Hi all,
I have a query related to exchanging roting information.
Initially I have enabled multicast dense mode . Now i want to change it to multicast sparse mode. My question is whether multicast sparse mode get\\use the routing information created by dense mode?
Harish,
Good question. I think the answer can differ, depending on how you migrate. You'll probably want to lab it up and experiment with different ways to migrate (some routers in dense or sparse-only, some routers with an interface in dense and another in sparse, etc..). Let us know how it goes.

What about sparse-dense mode, during migration? Methinks that will take care of it for you.
AFAIK, the multicast routing table is the multicast routing table - ie it doesn't matter if it's sparse or dense - it should all be there. sho ip mroute
After thinking about this more, I don't think it will be to big of an issue. Without the 'no ip pim dm-fallback' command configured, sparse mode will fall back to dense mode when an RP isn't reachable. So you might want to wait to bring your RP online until everyone is configured in sparse mode. Just a thought.
