Usage
Information
IS-IS normally purges LSPs with an incorrect data link checksum causing the LSP
source to regenerate the message. A cycle of purging and regenerating LSPs can
occur when a network link continues to deliver accurate LSPs even though there is
a link causing data corruption. This process could cause disruption to your system
operation.

To disable IS-IS on an interface, use the no ip router isis [tag] command.
Parameters

routing process. If you do not specify a tag, a null tag is
assigned.
