obtained from IGMP, along with a multicast routing protocol (such as PIM)

to support IP multicasting across the Internet. These routers may be

dynamically discovered by the switch or statically assigned to an interface

on the switch. To show all the interfaces attached to a multicast router:

1.

Click Multicast, IGMP Snooping, Multicast Router.
