Network requirements
z As shown in Figure 3-4, Router A connects to the IPv6 multicast source through Ethernet 1/0/2 and
to Switch A through Ethernet 1/0/1. Router A is the MLD querier on the subnet.
z MLDv1 is required on Router A, MLD snooping version 1 is required on Switch A, and Router A will
act as the MLD querier on the subnet.
z It is required that the receivers, Host A and Host B, attached to Switch A can receive IPv6 multicast
traffic addressed to IPv6 multicast group FF1E::101 only.
z It is required that IPv6 multicast data for group FF1E::101 can be forwarded through Ethernet 1/0/3
and Ethernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving
IPv6 multicast data.
