Use the Multicast > IGMP Snooping > Multicast Router (Add) page to
statically attach an interface to a multicast router/switch.
Depending on network connections, IGMP snooping may not always be able
to locate the IGMP querier. Therefore, if the IGMP querier is a known
multicast router/switch connected over the network to an interface (port or
trunk) on the switch, the interface (and a specified VLAN) can be manually
configured to join all the current multicast groups supported by the
attached router. This can ensure that multicast traffic is passed to all the
appropriate interfaces within the switch.
