Network requirements
As shown in Figure 199, Router A, which acts as the MLD querier on the subnet,
connects to the IPv6 multicast source through Ethernet1/1/2 and to Switch A (a
Switch 8800) through Ethernet1/1/1. While no IPv6 multicast protocol is running
on Router B, perform the following configuration so that Switch A can forward all
the received IPv6 multicast data to Router B.

Configuration procedure
1 Configure the IPv6 address of each interface
Configure an IP address and address prefix for each interface. The specific
configuration procedure is omitted here.
2 Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface, and enable
MLDv1 on Ethernet1/1/1.
<RouterA> system-view
[RouterA] multicast ipv6 routing-enable
[RouterA] interface ethernet 1/1/1
[RouterA-Ethernet1/1/1] mld enable
[RouterA-Ethernet1/1/1] mld version 1
