Syntax
ignore-lsp-checksum-error
undo ignore-lsp-checksum-error
View
IS-IS view
Parameter
None
Description
Use the ignore-lsp-checksum-error command to set IS-IS to drop the LSP when it
detects LSP checksum errors.
Use the undo ignore-lsp-checksum-error command to set IS-IS to ignore LSP
checksum errors.
IS-IS ignores LSP checksum errors by default.
When the local IS-IS receives a LSP packet, it will check the LSP packet and compare
the checksum calculated with that in the LSP packet. By default, the LSP packets will
not be dropped even if the checksum is wrong. You can use the
ignore-lsp-checksum-error to configure IS-IS to drop the LSP packet in case of
checksum error.
Example
# Configure IS-IS to drop the LSP packet in case of checksum error.
<3Com> system-view
System View: return to User View with Ctrl+Z.
