When multicast (PIM) routing is enabled, you can configure sparse mode or dense mode
operation on any FortiGate interface.
To view and edit PIM settings, go to Router > Dynamic > Multicast. The web-based
manager offers a simplified user interface to configure basic PIM options. You can also
configure advanced PIM options through the CLI. For more information, see the "router"

Add Static RP If required for sparse mode operation, enter the IP address of a Rendezvous

If an RP for the specified IP's multicast group is already known to the Boot
Strap Router (BSR), the RP known to the BSR is used and the static RP
address that you specify is ignored.
Apply Save the specified static RP addresses.
