Introduction to IPv6 Multicast VLAN
As shown in
, in the traditional IPv6 multicast programs-on-demand mode, when hosts, Host
A, Host B and Host C, belonging to different VLANs require IPv6 multicast programs on demand service,
the Layer 3 device, Router A, needs to forward a separate copy of the multicast traffic in each user
VLAN to the Layer 2 device, Switch A. This results in not only waste of network bandwidth but also extra
burden on the Layer 3 device.
Figure 1-1 Multicast transmission without IPv6 multicast VLAN
The IPv6 multicast VLAN feature configured on the Layer 2 device is the solution to this issue. With the
IPv6 multicast VLAN feature, the Layer 3 device needs to replicate the multicast traffic only in the IPv6
