I've been exploring multicast control using CGMP on Catalyst
switches. I see that CGMP is on by default, and creates lists of hosts
who have joined multicast groups and forwards multicast packets only
out ports to those hosts. The fast leave feature decreases the time it
akes for a host top be deleted from a group, or is it the time it akes
to delet a group.
Anyway, my real question is that all the documentation states that
this must work in conjunction with a router enabled with CGMP. Does
this mean a router with PIM enabled on its interfaces? I'm a little
confused. I thought PIM used IGMP.
Or can you enable CGMP on routers without PIM. OR does PIM invoke
both?
AHHHHHHHHHHHHH!!!!! Cisco brain freeze!
