Important Considerations

This display contains the summary information plus three additional fields: interface, metric, and ASEType.

Your system has one unified IP routing table. Routing policies allow you to control the flow of information among the network, the protocols, and the routing tables on your system.

There are two classes of routing policies:

Import policies — Control which OSPF non-self-originated external routes are stored in the routing table. OSPF import policies control only what the local router uses. They do not affect the propagation of non-self-originated external routes to other routers.

Export policies — Used on OSPF boundary routers to control which self-originated external routing updates are placed in the link-state database for propagation over the network. In this way, export policies govern what other routers learn with regard to the local boundary router’s self-originated information.

The system tracks policies that you define in both OSPF and Routing Information Protocol (RIP), so the indexes that are assigned to your policies may have gaps. For example, if you have OSPF policies 1 and 2, and RIP policies 3 through 6, the next policy is 7.

Fields in the IP OSPF Policy Detail Display

Field

Description

 

 

Action

Type 1 as default. Only applicable to export policies.

Index

Index number of the policy

Interface

Origin interface (only applicable when specifying direct as

 

Origin Protocol)

Metric

Adjustment to the cost metric of routes that match the policy

Protocol
