The following describes a scenario where a multicast frame is flooded on all ports of all switches. The switches and hosts in the
network need not receive these frames because they are not the intended destinations.
With multicast flood control, multicast frames, whose destination is not known, are forwarded only to the designated mrouter
port. OS10 learns of the mrouter interface dynamically based on the interface where an IGMP membership query is received.
You can also statically configure the mrouter interface using the ip igmp snooping mrouter and ipv6 mld snooping
mrouter commands.
