Multicast Router Configuration
In addition to building and maintaining lists of multicast group memberships, the Snooping
switch also maintains a list of multicast routers. When forwarding multicast packets, they
should be forwarded on ports that have joined using MLD/IGMP and also on ports on which
multicast routers are attached. In MLD/IGMP, there is only one active querier. This means
that all other routers on the network are suppressed and are not detectable by the switch. If a
query is not received on an interface within a specified length of time (multicast router
present expiration time), then that interface is removed from the list of interfaces with
multicast routers attached. The multicast router present expiration time is configurable via
management. The default value for the multicast router expiration time is zero, which
indicates an infinite timeout, that is, no expiration.
