Chapter 12 Configuring Multicast Routing
PIM
Rendezvous Points
When you configure PIM, you must choose one or more routers to operate as the RP. An RP is a single,
common root of a shared distribution tree and is statically configured on each router. 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).
You can configure more than one RP, but you cannot have more than one entry with the same RP.
Fields
• Generate IOS compatible register messages—Check this check box if your RP is a Cisco IOS router.
The security appliance software accepts register messages with the checksum on the PIM header and
only the next 4 bytes rather than using the Cisco IOS software method—accepting register messages
with the checksum on the entire PIM message for all PIM message types.
