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.
