Figure 30 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 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.
•
On Switch B, VLAN 10 is an IPv6 multicast VLAN.
All the user ports are hybrid ports and are assigned to VLAN 10.
MLD snooping is enabled for the IPv6 multicast VLAN and VLAN 2 through VLAN 4.
Figure 31 Port-based IPv6 multicast VLAN
Source
MLD snooping manages the router ports and member ports in the IPv6 multicast VLAN. When
Switch B receives an MLD message from a user port, it tags the message with the IPv6 multicast
VLAN ID and sends it to the MLD querier. When Switch A receives IPv6 multicast data from the
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.
