Network requirements
As shown in Figure 177, Router A connects to the IPv6 multicast source through
GigabitEthernet 1/0/2 and to Switch A through GigabitEthernet 1/0/1. Router A is
the MLD querier on the subnet.
Perform the following configuration so that multicast data can be forwarded
through GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 even if Host A and Host
B temporarily stop receiving IPv6 multicast data for some unexpected reasons.

Configuration procedure
1 Enable IPv6 forwarding and configure the IPv6 address of each interface
Enable IPv6 forwarding and configure an IPv6 address and prefix length for each
interface as per Figure 177. The detailed configuration steps are omitted.
2 Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface, and enable
MLDv1 on GigabitEthernet 1/0/1.
