170 CHAPTER 5: USING ROUTING PROTOCOL COMMANDS
By default, the checksum error of LSP is not 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, if the checksum in the
packet is found not in consistent with the calculated result, the LSP is 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.
Example
Ignore the checksum error of LSP.

Parameter
protocol: Specify the source protocol for importing the routing information,
which can be direct, static, rip, bgp, and ospf etc.
value: Specify the metric of the imported route, ranging from 0 to 63.
type external: Configure to set external cost type for routes imported by IS-IS.
type internal: Configure to set internal cost type for routes imported by IS-IS.
level-1: Configure to import the route into Level-1 routing table.
level-2: Configure to import the route into Level-2 routing table.
level-1-2: Configure to import the route into Level-1 and Level-2 routing table.
If the level is not specified, it defaults to importing the routes into level-1-2.
route-policy route-policy-name: Configure to import the routes matching
the conditions defined in the specified route-policy only.
Description
■ Use the import-route command to configure IS-IS to import the routing
information of other protocols.
■ Use the undo import-route command to cancel this function.
