Conguring S,G Expiry Timers
By default, S, G entries expire in 210 seconds. You can congure a global expiry time (for all [S,G] entries) or congure an expiry time for a
particular entry.
If you congure both, the ACL supersedes the global conguration for the specied entries.
When you create, delete, or update an expiry time, the changes are applied when the keep alive timer refreshes.
To congure a global expiry time or to congure the expiry time for a particular (S,G) entry, use the following commands.
1 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.
2 Set the expiry time for a specic (S,G) entry (as shown in the following example).
CONFIGURATION mode
ip pim sparse-mode sg-expiry-timer seconds sg-list access-list-name
The range is from 211 to 86,400 seconds.
The default is 210.
Example Conguring an (S,G) Expiry Time
NOTE
: The expiry time conguration is nullied and the default global expiry time is used if:
• an ACL is specied in the ip pim sparse-mode sg-expiry-timer command, but the ACL has not been created or is a
standard ACL.
• if the expiry time is specied for an (S,G) entry in a deny rule.
