Figure 81 Sub-VLAN-based multicast VLAN
MLD snooping manages router ports in the IPv6 multicast VLAN and member ports in each
sub-VLAN. When Switch A receives IPv6 multicast data from the IPv6 multicast source, it sends only
one copy of the IPv6 multicast data to the IPv6 multicast VLAN on Switch B. Then, Switch B sends a
separate copy to each sub-VLAN of the IPv6 multicast VLAN.
Port-based IPv6 multicast VLAN
As shown in
•
Host A, Host B, and Host C are in VLAN 2 through VLAN 4, respectively. All the user ports
(ports with attached hosts) on Switch B are hybrid ports.
•
On Switch B, VLAN 10 is an IPv6 multicast VLAN. All the user ports are assigned to VLAN 10.
•
MLD snooping is enabled for the IPv6 multicast VLAN and its sub-VLANs.

MLD snooping manages the router ports and member ports in the IPv6 multicast VLAN. When
Switch A receives IPv6 multicast data from the IPv6 multicast source, it sends only one copy of the
IPv6 multicast data to the IPv6 multicast VLAN on Switch B. Then, Switch B sends a separate copy
to each user port in the IPv6 multicast VLAN.
