[SwitchB] display ipv6 multicast-vlan group
Total 1 entries.
IPv6 multicast VLAN 10: Total 1 entries.
(::, FF1E::101)
Sub-VLANs (3 in total):
VLAN 2
VLAN 3
VLAN 4
The output shows that IPv6 multicast group FF1E::101 belongs to IPv6 multicast VLAN 10. IPv6
multicast VLAN 10 contains sub-VLANs VLAN 2 through VLAN 4. Switch B will replicate the IPv6
multicast data of VLAN 10 to VLAN 2 through VLAN 4.
Port-based IPv6 multicast VLAN configuration example
Network requirements
As shown in
•
Layer 3 device Switch A runs MLDv1 and acts as the MLD querier. Layer 2 device Switch B runs
MLDv1 snooping.
•
The IPv6 multicast source sends IPv6 multicast data to IPv6 multicast group FF1E::101.
Receivers Host A, Host B, and Host C belong to VLAN 2, VLAN 3, and VLAN 4, respectively.
Configure a port-based IPv6 multicast VLAN on Switch B to meet the following requirements:
•
Switch A sends 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.
