Commands
ignore-lsp-errors
e
Ignore LSPs with bad checksums instead of purging those LSPs.
Syntax
ignore-lsp-errors
To return to the default values, enter no ignore-lsp-errors.
Defaults
In IS-IS, the default deletes LSPs with internal checksum errors (no ignore-lsp-errors).
Command Modes
ROUTER ISIS
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 could
cause disruption to your system operation.
