IPv6 group policy configuration example
Network requirements
As shown in Figure 37, Router A runs MLDv1 and serves as the MLD querier, and Switch A runs MLDv1
snooping.
To enable Host A and Host B to receive only the IPv6 multicast data addressed to the IPv6 multicast group
FF1E::101, configure MLD snooping on Switch A and enable the switch to drop unknown IPv6 multicast
data instead of flooding it in VLAN 100.

Configuration procedure
1. Assign an IPv6 address and prefix length to each interface according to Figure 37. (Details not
shown.)
2. On Router A, enable IPv6 multicast routing, enable MLD on Ten-GigabitEthernet 1/0/1, and
enable IPv6 PIM-DM on each interface.
