Viewing and editing multicast settings
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”
chapter of the FortiGate CLI Reference.

Routing
Select to enable PIM version 2 routing. A firewall policy must be created on
PIM-enabled interfaces to pass encapsulated packets and decapsulated data
between the source and destination,
Add Static RP If required for sparse mode operation, enter the IP address of a Rendezvous
Point (RP) that may be used as the root of a packet distribution tree for a
multicast group. Join messages from the multicast group are sent to the RP,
and data from the source is sent to the RP.
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.
Create New Create a new multicast entry for an interface.
You can use the new entry to fine-tune PIM operation on a specific FortiGate
interface or override the global PIM settings on a particular interface. For
more information, see “Overriding the multicast settings on an interface” on
page 374.
