must be from 224.0.0.0 to 239.255.255.255.

The following table shows the modes in which this feature is available:
Multicast Route
Defining static multicast routes lets you separate multicast traffic from unicast traffic. For example,
when a path between a source and destination does not support multicast routing, the solution is to
configure two multicast devices with a GRE tunnel between them and to send the multicast packets over
the tunnel.
Static multicast routes are local to the security appliance and are not advertised or redistributed.
Fields
• Multicast Route—Displays the statically-defined multicast routes on the security appliance.
Double-clicking an entry in the table opens the Add/Edit Multicast Route dialog box for that entry.
– Source Address—Displays the IP address and mask, in CIDR notation, of the multicast source.
– Source Interface—Displays the incoming interface for the multicast route.
– Destination Interface—Displays the outgoing interface for the multicast route.
– Admin Distance—Displays the administrative distance of the static multicast route.
• Add—Opens the Add/Edit Multicast Route dialog box. Use this button to add a new static route.
