3Com S7906E Configuration Manual page 1275

It is required to 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.

Figure 1-9 Network diagram for MLD proxying configuration
Configuration procedure
1) Enable IPv6 forwarding and configure the IPv6 addresses
Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length of each
interface as per Figure
2) Enable IPv6 multicast routing, IPv6 PIM-DM, MLD, and MLD proxying respectively.
# Enable IPv6 multicast routing on Switch A, IPv6 PIM-DM on VLAN-interface 101, and MLD on
VLAN-interface 100.
<SwitchA> system-view
[SwitchA] multicast ipv6 routing-enable
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim ipv6 dm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] mld enable
[SwitchA-Vlan-interface100] pim ipv6 dm
[SwitchA-Vlan-interface100] quit
# Enable IPv6 multicast routing on Switch B, MLD proxying on VLAN-interface 100, and MLD on
VLAN-interface 200.
<SwitchB> system-view
[SwitchB] multicast ipv6 routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] mld proxying enable
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] mld enable
[SwitchB-Vlan-interface200] quit
