Chapter 64 Configuring Routing Policies
OSPF Routing on Cisco IOS Routers
A router that has interfaces in multiple OSPF areas is called an Area Border Router (ABR). An ABR
uses LSAs to send information about available routes to other OSPF routers. A router that acts as a
gateway to redistribute traffic between routers using OSPF and routers using other routing protocols is
called an Autonomous System Boundary Router (ASBR). Any router can act as an ABR or ASBR.
The following topics describe the tasks you perform to create an OSPF routing policy:
• Defining OSPF Process Settings, page 64-20
• Defining OSPF Area Settings, page 64-21
• Redistributing Routes into OSPF, page 64-22
• Defining OSPF Interface Settings, page 64-25

Defining OSPF Process Settings
You configure OSPF process parameters by specifying a process ID number, which identifies the OSPF
process to other routers, and by deciding whether any interfaces should be passive. Passive interfaces do
not send routing updates to their neighbors.

Step 1 Do one of the following:
• (Device view) Select Platform > Routing > OSPF Process from the Policy selector, then click the
Setup tab in the work area.
• (Policy view) Select Router Platform > Routing > OSPF Process from the Policy Type selector.
Select an existing policy or create a new one, and then click the Setup tab.
The OSPF Process Setup tab is displayed. See Table 64-13 on page 64-35 for a description of the fields
on this tab.
Step 2 On the OSPF Process Setup tab, select an OSPF process from the table, then click Edit, or click Add to
create a process. The OSPF Setup dialog box appears. See Table 64-14 on page 64-36 for a description
of the fields in this dialog box.
Step 3 Enter the process ID number in the field provided. The process ID defined here does not need to match
the process ID on any other devices.
Step 4 Define which interfaces should not send routing updates to its neighbors:
a. Click Edit under Passive Interfaces to display the Edit Interfaces dialog box. Use this dialog box to
define which interfaces should not send routing updates to its neighbors.
