Multicast Forwarding
Multicast forwarding enables one-to-many information dissemination. Multicast applications are useful for
dissemination of information to multiple clients, where clients do not require reception of the entire content.
A typical application is a cable-TV-like service, where clients can join a channel in the middle of a
transmission, and leave before it ends.
The data is sent only to relevant ports. Forwarding the data only to the relevant ports conserves bandwidth
and host resources on links.
By default, all Multicast frames are flooded to all ports of the VLAN. It is possible to selectively forward only
to relevant ports and filter (drop) the Multicast on the rest of the ports by enabling the Bridge Multicast
filtering status in the Multicast > Properties page.
