Description
Use the
ignore-lsp-checksum-error
command to configure the IS-IS to discard LSPs
with checksum errors.
Use the
undo ignore-lsp-checksum-error
command to configure the IS-IS to ignore
the checksum error of LSP.
By default, the checksum error of LSP is ignored.
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, even if the checksum in the packet is
found not in consistent with the calculated result, the LSP is processed as normal.
However, after not ignoring LSP checksum error is set with the
ignore-lsp-checksum-error
command, the LSP packet will be discarded silently if the
checksum error is found.
Example
# Discard the LSPs with checksum errors.

Parameter
protocol
: Specifies the source protocol for importing the routing information, which can
be direct, static, rip, bgp, ospf, ospf-ase, and ospf-nssa.
value
: Specifies the metric of the imported route, ranging from 0 to 63.
type
: Type of routing cost:
internal
indicates the routing cost in the same area;
external
indicates the routing cost among areas. By default, the routing cost is
internal
.
level-1
: Configures to import the route into Level-1 routing table.
level-2
: Configures to import the route into Level-2 routing table. If the level is not
specified, it defaults to importing the routes into
level-2
.
