View This command can be used in the following views:
■ IS-IS view
Description After receiving an LSP packet, the local IS-IS will calculate its checksum and compares
the result with the checksum in the LSP packet. This process is the checksum
authentication over the received LSP. By default, if the checksum in the packet is
found not in consistent with the calculated result, the LSP will be discarded without
being processed. Moreover, if ignoring checksum error is set with the
ignore-lsp-checksum-error
command, the packet will be processed as a
normal one even if the checksum error is found.
