Figure 30 Port-based IPv6 multicast VLAN
After the configuration, upon receiving an MLD message on a user port, Switch A tags the message with
the IPv6 multicast VLAN ID and relays it to the MLD querier, so that MLD snooping can uniformly manage
the router ports and member ports in the IPv6 multicast VLAN. When forwarding multicast data to Switch
A, Router A needs to send only one copy of multicast traffic to Switch A in the IPv6 multicast VLAN, and
Switch A distributes the traffic to all member ports in the IPv6 multicast VLAN.
NOTE:
•
For more information about MLD snooping, router ports, and member ports, see the chapter “MLD
snooping configuration.”
• For more information about VLAN tags, see the Layer 2—LAN Switching Configuration Guide.
IPv6 multicast VLAN configuration task list
Complete the following tasks to configure IPv6 multicast VLAN:
Configuration task Remarks
Configuring user port attributes Required
Configuring IPv6 multicast VLAN ports Required
Configuring port-based IPv6 multicast VLAN
When configuring port-based IPv6 multicast VLAN, you need to configure the attributes of each user port
and then assign the ports to the IPv6 multicast VLAN.
NOTE:
•
A user port can be configured as a multicast VLAN port only if it is of the Ethernet, or Layer 2 aggregate
interface type.
• In Layer 2 Ethernet interface view or Layer 2 aggregate interface view, the configuration is effective on
only the current interface. In port group view, the configuration is effective on all ports in the current port
group.
