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.
ip router isis
Configure IS-IS routing processes on an interface and attach an area tag name to the routing process.
Syntax
ip router isis [tag]
To disable IS-IS on an interface, use the no ip router isis [tag] command.
Parameters
tag (OPTIONAL) The tag you specify identifies a specific area routing process. If you
do not specify a tag, a null tag is assigned.
