IPv6 PIM-DM runs on the core network.
•
Host A and Host C on the stub network receive VOD information destined to IPv6 multicast
group FF3E::101.
Configure the MLD proxying feature on Switch B so that Switch B can maintain group memberships
and forward IPv6 multicast traffic without running IPv6 PIM-DM.

Configuration procedure
1.
Assign an IPv6 address and prefix length to each interface, as shown in
. (Details not
shown.)
2.
Enable IPv6 multicast routing, IPv6 PIM-DM, MLD, and MLD proxying:
# On Switch A, enable IPv6 multicast routing.
<SwitchA> system-view
[SwitchA] ipv6 multicast routing
[SwitchA-mrib6] quit
# Enable IPv6 PIM-DM on VLAN-interface 101.
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 pim dm
[SwitchA-Vlan-interface101] quit
# Enable MLD on VLAN-interface 100.
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] mld enable
[SwitchA-Vlan-interface100] quit
# On Switch B, enable IPv6 multicast routing.
<SwitchB> system-view
[SwitchB] multicast ipv6 routing-enable
[SwitchB-mrib6] quit
# Enable MLD proxying on VLAN-interface 100.
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] mld proxying enable
[SwitchB-Vlan-interface100] quit
# Enable MLD on VLAN-interface 200.
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] mld enable
