Sub-VLAN-based IPv6 multicast VLAN configuration

Network requirements
As shown in Figure 32:
• MLDv1 runs on Layer 3 device Switch A, and MLDv1 snooping runs on Layer 2 device Switch
B.
• Switch A acts as the MLD querier.
• The IPv6 multicast source sends IPv6 multicast data to IPv6 multicast group FF1E::101. Host A,
Host B, and Host C are receivers. They belong to VLAN 2 through VLAN 4, respectively.
Configure a sub-VLAN-based IPv6 multicast VLAN on Switch B to achieve the following goals:
• Switch A sends the IPv6 multicast data to Switch B through the IPv6 multicast VLAN.
• Switch B forwards the IPv6 multicast data to the receivers in different user VLANs.
