3Com S7906E Configuration Manual page 1314

Switch D connects to the network that comprises the multicast source (Source) through
VLAN-interface 300.
Switch A connects to N1 through VLAN-interface 100, and to Switch D through VLAN-interface
103.
Switch B and Switch C connect to N2 through their respective VLAN-interface 200, and to Switch D
through VLAN-interface 101 and VLAN-interface 102 respectively.
MLDv1 is to run between Switch A and N1, and between Switch B/Switch C and N2.

Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing
Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each
interface as per Figure
Configure OSPFv3 for interoperation among the switches in the PIM-DM domain. Ensure the
network-layer interoperation in the PIM-DM domain and enable dynamic update of routing information
among the switches through an IPv6 unicast routing protocol. Detailed configuration steps are omitted
here.
2) Enable IPv6 multicast routing, and enable IPv6 PIM-DM and MLD
# Enable IPv6 multicast routing on Switch A, enable IPv6 PIM-DM on each interface, and enable MLD
on VLAN-interface 100, which connects Switch A to N1.
