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.
