isis psnp-interval
Sets the transmission interval for the partial sequence number packet on a point-to-point interface.
Syntax: isis psnp-interval seconds [level-1 | level-2]
no isis psnp-interval
seconds
Seconds between transmission of partial sequence number PDU. Valid values are 0 - 65535.
level -l
Configures the interval for Level 1 interfaces.
level -2
Configures the interval for Level 2 interfaces.
Description: After a router has established an adjacency with a neighboring router, it periodically transmits link-state information to ensure synchronization of routing tables throughout the network. Increasing the time between the transmission of each PSNP packet increases reduces the chances of overloading the network if a large number of PSNPs are being transmitted.
Use the isis psnp-interval seconds command to configure number of seconds between retransmissions of PSNPs on this interface. If no level is specified, the command configures the interval for level-1 routing only.
Use the isis psnp-interval seconds or the isis psnp-interval seconds level-1 command to configure the retransmission interval for level-1 (intra-area) routing.
Use the isis psnp-interval seconds level-2 command to configure the retransmission interval for level-2 (inter-area) routing.
Use the no isis psnp-interval command to set the retransmission interval at the default value of 2 seconds.
Factory Default: 2 seconds.
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 psnp-interval seconds command sets the retransmission for Level-1 PSNPs for the interface to 30 seconds.
- The show running-config interface command displays the setting:
router(config)#router isis 0
router(config-router)#net 49.0001.0000.0000.1111.00
router(config-router)#interface pos 1/5/1
router(config-if)#ip router isis 0
router(config-if)#isis psnp-interval 30
router(config-if)#end
router#sho run int
