OSPF Routing on Cisco IOS Routers
Defining OSPF Interface Settings
You can modify a variety of interface-specific OSPF parameters. This procedure describes how to define
these parameters. For more information about a particular parameter, see the following topics:
•Understanding Interface Cost, page 64-26
•Understanding Interface Priority, page64-26
•Disabling MTU Mismatch Detection, page 64-27
•Understanding OSPF Timer Settings, page 64-28

Step 1 Do one of the following:
•(Device view) Select Platform > Routing > OSPF Interface from the Policy selector.
•(Policy view) Select Router Platform > Routing > OSPF Interface from the Policy Type selector.
Select an existing policy or create a new one.
The OSPF Interface page is displayed. See Table 64-11 on page 64-30 for a description of the fields on
this page.
Step 2 On the OSPF Interface page, select an interface definition from the table, then click Edit, or click Add
to create a definition. The OSPF Interface dialog box appears. See Table64-12 on page 64-32 for a
description of the fields in this dialog box.
Step 3 Enter the name of the interface or interface role to define, or click Select to select an interface role from
a list or to create a new one. For more information, see Specifying Interfaces During Policy Definition,
page 6-70.
Step 4 Define interface authentication. The authentication type you select for the interface must match the
authentication type you select for the area (see Defining OSPF Area Settings, page 64-21).
All neighboring routers on the same network must have the same password to be able to exchange OSPF
information. For more information, see Understanding OSPF Interface Authentication, page 64-29.
The key ID number can be associated with multiple passwords. This is an easy and secure way to migrate
passwords. For example, to migrate from one password to another, configure a password under a
different key ID, then remove the first key.
