Usage Guidelines

Usage Scenario

When importing routes to IS-IS, you can use the apply isis command to set the level of the routes imported to IS-IS.

To import routes to the OSPF backbone area or an NSSA, run the apply ospf command, which prevents too many external routes from being imported into OSPF.

Prerequisites

A route-policy has been configured using the route-policy command.

Configuration Impact

After a route matches a route-policy, the level of the route imported to IS-IS is set.

Routes matching the if-match clauses defined in the route-policy will be imported into the OSPF area specified in the command.

Example

# Import routes into the OSPF backbone area.

<HUAWEI> system-view
[~HUAWEI] route-policy policy permit node 10
[*HUAWEI-route-policy] apply ospf backbone

# Set the level of the routes imported to IS-IS.

<HUAWEI> system-view
[~HUAWEI] route-policy policy permit node 10
[*HUAWEI-route-policy] apply isis level-1
