Configuring PIM
PIM Page - Rendezvous Points Tab
When you configure PIM, you must choose one or more routers or routing devices to operate as the RP.
An RP is a single, common root of a shared distribution tree and is statically configured on each device.
First hop routers use the RP to send register packets on behalf of the source multicast hosts.
You can configure a single RP to serve more than one group. If a specific group is not specified, the RP
for the group is applied to the entire IP multicast group range (224.0.0.0/4).
Use the Rendezvous Points panel to define rendezvous points. You can configure more than one RP, but
you cannot have more than one entry with the same RP.
Navigation Path
You access the Rendezvous Points tab from the PIM page. For more information, see Configuring PIM,
page 53-11.

compatible register messages
Check this box if your rendezvous point is a Cisco IOS router. The
security appliance software accepts register messages with the
checksum calculated on the PIM header and only the next 4 bytes, while
Cisco IOS software accepts register messages with the checksum
calculated on the entire PIM message for all PIM message types.
Rendezvous Points table Lists the rendezvous points currently configured on the security
