ROUTER ISIS
Command
History
Version 9.0(1.3) Introduced on the S5000.
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.
S5000
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.
Defaults No processes are configured.
