Usage Guidelines

Usage Scenario

The apply ospf command can be used to specify the OSPF backbone area or NSSA area to which routes are imported. This can prevent too many external routes from being imported into OSPF and bringing heavy stress on OSPF devices.

Prerequisites

The route-policy command has been run.

Configuration Impact

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

Example

# Import routes into the OSPF backbone area.

<sysname> system-view

[sysname] route-policy policy permit node 10

[sysname-route-policy] apply ospf backbone
