Syntax
import-route protocol [ cost value | route-policy route-policy-name ]*
undo import-route protocol
View
RIP view
Parameter
protocol: Source routing protocol whose routes will be imported by RIP. At present,
RIP can import the following types of routes: direct, ospf, ospf-ase, ospf-nssa,
static, isis and bgp.
value: Cost value of the routes to be imported, in the range of 1 to 16.
route-policy route-policy-name: Name of a routing policy, containing 1 to 19
characters.Specifies to import only the routes matching the conditions of the specified
route-policy
Description
Use the import-route command to import the routes of another protocol into RIP.
Use the undo import-route command to cancel the routes imported from another
protocol.
By default, RIP does not import routes from other protocols.
The import-route command is used to import the routes of another protocol with a
specified cost.. RIP regards the imported routes as its own routes and transmits them
with the specified cost. This command can greatly enhance the capability of RIP to
obtain routes, thereby improving RIP performance.
If the cost value is not specified, routes will be imported with the default routing cost
(set by the default cost command, ranging from 1 to 16). If the cost of an imported
route is 16, RIP marks the route as HOLD DOWN (however, the route can still be used
to forward packets), and continues to announce the route with this cost to other
routers running RIP until the Garbage Collection timer times out (the timeout time
defaults to 120 seconds).
Related command: default cost.
Example
# Import static routes with the cost of 4.
