Port-based IPv6 multicast VLAN
As shown in Figure 93:
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.
Figure 93: Port-based IPv6 multicast VLAN
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.
