I've been going over some multicast configurations and need some
clarification.
I've been configuring PIM both dense and sparse, and have used the
IP IGMP JOIN X.X.X.X command to check multicast routing, buit I didn't
think it was required to route mulitcasts to hosts off of router
interfaces.
In Caslow's book it says that IGMP JOIN must be enabled on an
interface for it to route multicast packets to hosts on that interface
who want to join a (that?) group, or that is my interpretation. The
Cisco CD examples don't show this. They have the global IP MULTICAST,
the interface PIM commands, and RP commands if neccessary.
Is the join command required to route muticasts to host off of
interfaces? Can anyone clear up my confusion, as I have not done
multicast routing out of the lab.
Thanks!
