IPv6 multicast data for group FF1E::101 can be forwarded through GigabitEthernet 1/0/3 and
GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving
IPv6 multicast data, and that Switch A drops unknown IPv6 multicast data and does not broadcast the
data to the VLAN where Switch A resides.
