Multicast Router Port Configuration
The multicast router port is the port which is directly connected to a multicast router. A
switch adds multicast router ports to the forwarding table to forward membership reports
only to those ports. Multicast router ports can be statically specified or dynamically
learned by incoming IGMP queries and PIM hello packets.
Static Multicast Router Port
You can statically configure Layer 2 port as the multicast router port which is directly con-
nected to a multicast router, allowing a static connection to a multicast router.
