MULTICAST ROUTING COMMANDS

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 you should enable IGMP for any interface that is using multicast routing.)
