8.1.5 Multicast VLAN

In old multicast transmission mode, when users in different VLANs apply for join the same
multicast group, the multicast router will duplicate this multicast information and deliver each
VLAN owning a receiver one copy. This mode wastes a lot of bandwidth.
The problem above can be solved by configuring a multicast VLAN. By adding switch ports to the
multicast VLAN and enabling IGMP Snooping, you can make users in different VLANs share the
same multicast VLAN. This saves the bandwidth since multicast streams are transmitted only
within the multicast VLAN and also guarantees security because the multicast VLAN is isolated
from user VLANS.
