Enabling and Disabling IGMP Relay on a Downstream Router
An IGMP Relay device is a unicast router with an interface to a multicast router
and interfaces to one or more networks containing network hosts. A router
configured as an IGMP Relay device provides group registration services for an IP
multicast router in a PIM environment. For more information about IGMP Relay,
see Chapter 9, “Configuring IGMP Relay.”
By default, IGMP Relay support for downstream routers is disabled. When you
enable IGMP Relay support for a downstream router, PIM receives multicast data
from the downstream router, encapsulates the data within a register packet, and
sends the packets to the elected RP in the PIM domain.
To enable and disable IGMP Relay support for a downstream router, complete the
following tasks:
