As shown above, MLD Snooping is maintaining the router port in the IPv6 multicast VLAN
(VLAN 10) and the member ports in the sub-VLANs (VLAN 2 through VLAN 4).
Port-Based Multicast VLAN Configuration Example
Network requirements
z As shown in Figure 10-5 , Router A connects to an IPv6 multicast source (Source) through
GigabitEthernet 2/0/1, and to Switch A through GigabitEthernet 2/0/2.
z MLDv1 is required on Router A. MLDv1 Snooping is required on Switch A. Router A acts as
the MLD querier.
z Switch A’s GigabitEthernet 2/0/1 belongs to VLAN 10, GigabitEthernet 2/0/2 through
GigabitEthernet 2/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through
Host C are attached to GigabitEthernet 2/0/2 through GigabitEthernet 2/0/4 of Switch A.
z 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.
z 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.
