You can configure a global expiry time (for all [S,G] entries) or configure an expiry time for aparticular entry.If you configure both, the ACL supersedes the global configuration for the specified entries.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 commands.1 Enable global expiry timer for S, G entries.CONFIGURATION modeip pim sparse-mode sg-expiry-timer secondsThe range is from 211 to 86,400 seconds.The default is 210.2 Set the expiry time for a specific (S,G) entry (as shown in the following example).CONFIGURATION modeip pim sparse-mode sg-expiry-timer seconds sg-list access-list-nameThe range is from 211 to 86,400 seconds.The default is 210.Example Configuring an (S,G) Expiry TimeNOTE: 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 astandard ACL.• if the expiry time is specified for an (S,G) entry in a deny rule.Dell(conf)#ip access-list extended SGtimerDell(config-ext-nacl)#permit ip 10.1.2.3/24 225.1.1.0/24Dell(config-ext-nacl)#permit ip any 232.1.1.0/24Dell(config-ext-nacl)#permit ip 100.1.1.0/16 anyDell(config-ext-nacl)#show conf!ip access-list extended SGtimerseq 5 permit ip 10.1.2.0/24 225.1.1.0/24seq 10 permit ip any 232.1.1.0/24seq 15 permit ip 100.1.0.0/16 anyDell(config-ext-nacl)#exitDell(conf)#ip pim sparse-mode sg-expiry-timer 1800 sg-list SGtimerTo display the expiry time configuration, use the show running-configuration pim command from EXEC Privilege mode.PIM Sparse-Mode (PIM-SM) 685
