Example Configuring an (S,G) Expiry Time

NOTE: The expiry time configuration is nullified and the default global expiry time is used if:

• an ACL is specified in the ip pim sparse-mode sg-expiry-timer command, but the ACL 

has not been created or is a standard ACL.

• if the expiry time is specified for an (S,G) entry in a deny rule.

Configuring a Static Rendezvous Point

The rendezvous point (RP) is a PIM-enabled interface on a router that acts as the root a group-specific 
tree; every group must have an RP.

• Identify an RP by the IP address of a PIM-enabled or Loopback interface.
