Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 12.1 for the QFX Series.
Description
Configure the interval between complete sequence number PDUs (CSNPs) on a LAN interface.
If the routing device is the designated router on a LAN, IS-IS sends CSN packets every 10 seconds. If the routing device is on a point-to-point interface, it sends CSN packets every 5 seconds. To protect against link-state PDU flooding, we recommend modifying the default interval.
To modify the CSNP interval, include the csnp-interval statement.
To configure the interface not to send any CSNPs, specify the disable option.
Default
By default, IS-IS sends CSNPs periodically. If the routing device is the designated router on a LAN, IS-IS sends CSNPs every 10 seconds. If the routing device is on a point-to-point interface, it sends CSNPs every 5 seconds.
Options
disable—Do not send CSNPs on this interface.
seconds—Number of seconds between the sending of CSNPs.
Range: 1 through 65,535 seconds
Default: 10 seconds on LAN broadcast links. 5 seconds on point-to-point links.
Required Privilege Level
routing—To view this statement in the configuration.
