undo import-route protocol
View

Parameter
protocol: Specify the source routing protocol to be imported by RIP. At present, RIP can
import the following routes: direct, bgp, ospf, ospf-ase, ospf-nssa and static.
value: Cost value of the route to be imported.
route-policy route-policy-name: Configure to import the route matching the condition
of the specified Route-policy only.
Description
Using import-route command, you can import the routes of other protocols into RIP.
Using undo import-route command, you can cancel the routes imported from other
protocols.
By default, RIP does not import any other route.
The import-route command is used to import the route of another protocol by using a
certain cost value. RIP regards the imported route as its own route and transmits it with
the specified cost value. This command can greatly enhance the RIP capability of
obtaining routes, thus increases the RIP performance.
If the cost value is not specified, routes will be imported according to the default cost
ranging from 1 to 16. If the imported route cost value is 16, then RIP continues to
announce this cost to other routers running RIP, and marks this route with HOLDDOWN.
However, this router can still forward packets until the Garbage Collection timer times
out (defaults to 120 seconds).
For the related commands, see default cost.
Example
# Import a static route with cost 4.
[Quidway-rip] import-route static cost 4
