Configuring S,G Expiry Timers
You can configure a global expiry time (for all [S,G] entries). By default, [S,G] entries expire in 210 seconds.
When you create, delete, or update an expiry time, the changes are applied when the keep alive timer refreshes.
To configure a global expiry time, use the following command.
Enable global expiry timer for S, G entries.
CONFIGURATION mode
ip pim sparse-mode sg-expiry-timer seconds
The range is from 211 to 86,400 seconds.
The default is 210.
NOTE: The global expiry time for all [S, G] entries can vary from 360 to 420 seconds.
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.
ip pim rp-address address group-address group-address mask [override]
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 configuration.
Use the following command if you have configured 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 configured RPs.
● Use the override option to use statically configured RP instead of the longest prefix match of the configured group
address associated with a dynamic RP.
ip pim rp-address address {group-address group-address mask} [override]
To display the assigned RP for a group, use the show ip pim rp [mapping | group-address] command from EXEC
privilege mode.
Following is an example of show ip pim rp command output:
DellEMC#show ip pim rp
