isis csnp-interval
Configures the number of seconds between transmission of CSNP packets for an interface.
Syntax: isis csnp-interval seconds [level-1 | level-2]
no isis csnp-interval
seconds
The interval of time between transmission of CSNPs on broadcast networks. This interval only applies to the designated router. This can be a number between 0 and 65535 seconds.
level-l
Configures the amount of time between transmission of CSNPs for Level 1 independently. If you do not specify a level, Level 1 is the default.
level-2
Configures the interval of time between transmission of CSNPs for Level 2 independently.
Description: On broadcast networks, designated routers send complete sequence number PDU (CSNP) packets to maintain database synchronization. The CSNP interval timer is the number of seconds between transmissions of CNSP packets from this interface.
The CSNP interval is configured independently for Level 1 and Level 2. This feature does not apply to point-to-point interfaces.
NOTE This value is configured only on routers you expect to act as designated router.
Use the isis cnsp-interval seconds level-1 command to configure the number of seconds between transmission of CSNPs on this interface for Level-1 adjacencies.
Use the isis cnsp-interval seconds level-2 command to configure the number of seconds between transmission of CSNPs on this interface for Level-2 adjacencies.
Use the no isis cnsp-interval command to configure the number of seconds between transmission of CSNPs on this interface at the default value of 10 seconds.
Factory Default: The default is 10 seconds for both Level 1 and Level 2 CSNP packets.
Command Mode: Interface configuration.
Example: In the following example:
- The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration.
- The net command configures a NET for the routing process.
- The interface pos n/n/n identifies a specific POS interface and changes the command mode to Interface configuration.
- The ip router isis command enables the IS-IS process specified by the global router isis command on the interface.
- The isis csnp-interval seconds level-1 command configures the transmission interval for CSNP packets for the interface at 15 seconds.
- The show running-config interface command displays the setting:
router(config)#router isis npi
router(config-router)#net 49.0001.0000.0000.1111.00
router(config-router)#interface gbe 1/5/1
router(config-if)#ip router isis npi
router(config-if)#isis csnp-interval 15 level-1
router(config-if)#end
router#show run int
