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
Group RP
225.0.1.40 165.87.50.5
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.
