Users Guide
Only congure interfaces as Level 1 or Level 2 on routers that are between areas (for example, a Level 1-2
router) to prevent the software from sending unused hello packets and wasting bandwidth.
isis csnp-interval
Congure the IS-IS complete sequence number PDU (CSNP) interval on an interface.
Syntax
isis csnp-interval seconds [level-1 | level-2]
To return to the default values, use the no isis csnp-interval [seconds] [level-1 |
level-2] command.
Parameters
seconds Interval of transmission time between CSNPs on multi-access networks for the
designated intermediate system. The range is from 0 to 65535. The default is 10.
level-1 (OPTIONAL) Independently congures the interval of time between transmission
of CSNPs for Level 1.
level-2 (OPTIONAL) Independently congures the interval of time between transmission
of CSNPs for Level 2.
Defaults seconds = 10; level-1 (if not otherwise specied)
