Multicast routing is a networking method for efficient distribution of one-to-many traffic, and is primarily used for audio and video streams. When you enable multicast routing on your Firebox, the Firebox is the local multicast router that forwards multicast traffic from the source to the devices on your network that receive the traffic.
For more information about multicast routing on your Firebox, see About Multicast Routing.
On the System Status > Multicast Routes page, you can see information about the multicast routes on your Firebox.
