Usage
Information
Because the default establishes Level 1 and Level 2 adjacencies, you do not need to
configure this command. Routers in an IS-IS system must be configured as a Level
1-only, Level 1-2, or Level 2-only system.
Only configure 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
Configure the IS-IS complete sequence number PDU (CSNP) interval on an interface.
Syntax

To return to the default values, use the no isis csnp-interval [seconds]
[level-1 | level-2] command.
Parameters
