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.
