Configuring S,G Expiry Timers
By default, S, G entries expire in 210 seconds. You can configure a global expiry time (for all [S,G]).
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 or to configure the expiry time for a particular (S,G) entry, 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.
Dell(conf)#ip pim sparse-mode sg-expiry-timer 1800
To display the expiry time configuration, use the show running-configuration pim command from EXEC Privilege
mode.
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
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 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 override bootstrap router updates with your static RP configuration.
ip pim rp-address
To display the assigned RP for a group, use the show ip pim rp command from EXEC privilege mode.
Dell#show ip pim rp
Group RP
