7.27 Multicast Routing Commands
This router uses IGMP snooping and query to determine the ports connected to
downstream multicast hosts, and to propagate this information back up through
the multicast tree to ensure that requested services are forwarded through each
intermediate node between the multicast server and its hosts, and also to filter
traffic from all of the other interfaces that do not require these services.
Multicast routers use snooping and query messages, along with a multicast
routing protocol to deliver IP multicast packets across different subnetworks.
This router supports both the Distance-Vector Multicast Routing Protocol
(DVMRP) and Protocol Independent Multicasting (PIM). (Note that IGMP should
be enabled for any interface that is using multicast routing.)
