I do not think it is turned on by default. ip multicast-routing is the
command to crank it up. by default, it will be sent out of all ports on
your Cats. We are using igmp snooping here. It is better than cgmp. We
once opened up a ticket to understand the difference.

Hi,
I have some users who want to use a multicast application between different
vlans.
Is multicast forwarding turned on by default on 12.1 IOS? Would'nt I need to
config
something like PIM, IGMP and CGMP on my cat's and routers to do this
efficiently
or will the IOS just flood multicast packets ou
