Hi,

Multicast traffic destined to a multicast MAC address, Only routers enabled multicast routing protocol can be member of this multicast MAC addresses and receive the traffic and do multicast routing. Non-multicast routers will drop the multicast packets at the layer2 itselft.

Thx

how do you enable multicast on the router? does it use a routing protocol ?

Yep, there are various multicast routing protocol. To enable multicast, in the global configuration mode you have to give ip multicast-routing...Rest of the configuration is depend upon the routing protocol you choose

can you give me example or scenario of this ?
