3Com 4510G Configuration Manual page 469

Switch A's GigabitEthernet 1/0/1 belongs to VLAN 10, GigabitEthernet 1/0/2 through
GigabitEthernet 1/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host C
are attached to GigabitEthernet 1/0/2 through GigabitEthernet 1/0/4 of Switch A.
The IPv6 multicast source sends IPv6 multicast data to IPv6 multicast group FF1E::101. Host A,
Host B, and Host C are receivers of the IPv6 multicast group.
Configure the port-based IPv6 multicast VLAN feature so that Router A just sends IPv6 multicast
data to Switch A through the IPv6 multicast VLAN and Switch A forward the IPv6 multicast data to
the receivers that belong to different user VLANs.

Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses
Enable IPv6 forwarding on each device and configure the IPv6 address and address prefix for each
interface as per Figure
2) Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface, and enable MLD on the
host-side interface GigabitEthernet 1/0/2.
