To display the expiry time conguration, use the show running-configuration [acl | pim] command from EXEC
Privilege mode.
Conguring a Static Rendezvous Point
The rendezvous point (RP) is a PIM-enabled interface on a router that acts as the root a group-specic tree; every group must have
an RP.
• Identify an RP by the IP address of a PIM-enabled or Loopback interface.
ip pim rp-address
Example of Viewing an RP on a Loopback Interface
Dell#sh run int loop0
!
interface Loopback 0
ip address 1.1.1.1/32
ip pim sparse-mode
no shutdown
Dell#sh run pim
!
ip pim rp-address 1.1.1.1 group-address 224.0.0.0/4
Overriding Bootstrap Router Updates
PIM-SM routers must know the address of the RP for each group for which they have (*,G) entry.
This address is obtained automatically through the bootstrap router (BSR) mechanism or a static RP conguration.
Use the following command if you have congured a static RP for a group. If you do not use the override option with the
following command, the RPs advertised in the BSR updates take precedence over any statically congured RPs.
• Use the override option to override bootstrap router updates with your static RP conguration.

Example of Viewing the Rendezvous Point (Multicast Group Range)
To display the assigned RP for a group, use the show ip pim rp command from EXEC privilege mode.
Dell#show ip pim rp

226.1.1.1 165.87.50.5
To display the assigned RP for a group range (group-to-RP mapping), use the show ip pim rp mapping command in EXEC
privilege mode.
