Network requirements
As shown in
acting as the MLD querier.
Host A and Host B can receive only IPv6 multicast data destined for IPv6 multicast group FF1E::101.
IPv6 multicast data for FF1E::101 can be forwarded through GigabitEthernet 3/1/3 and
GigabitEthernet 3/1/4 of Router B even if Host A and Host B temporarily stop receiving IPv6 multicast
data for some unexpected reasons. Router B drops unknown IPv6 multicast data and does not broadcast
the data to the VLAN where Router B resides.
