Important Considerations

The OSPF router ID identifies the router to other routers within an autonomous system. Three types of router identifiers are available; all three take the form of an IP address:

Default — A unique ID that the system generates and uses as the default router ID

Interface — The index of an IP interface on the router

Address — An ID that you define in the form of an IP address

OSPF routing must be inactive (disabled) before you can add or modify an OSPF router ID. To set the OSPF mode to disabled, see “ip ospf interface mode” earlier in this chapter. After you modify the router ID, you can set the OSPF mode to enabled on the interface

The router ID must be unique from all other router IDs and ip interfaces in the autonomous system for OSPF to operate correctly. Choose the default setting to ensure unique router IDs.

The resulting prompt depends on the router ID type that you choose.
