Setting OSPF Router IDs

Setting OSPF
Router IDs
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
— An arbitrary 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 (off) before you can add or modify an
OSPF router ID. To set the OSPF mode to off, see “Setting Modes” on
page 13-10 for details. After you add the router ID, set the OPSF mode to
active on the interface.
To set the router ID:
1
From the top level of the Administration Console, enter:
ip ospf routerID
The system displays the current router ID and the router ID type.
2
Enter the router ID type (
default
,
interface
, or
address
), or press
Return or Enter to accept the currently defined type.
3
Enter the interface or address for the router ID.
Example:
Current OPSF router id = 158.101.142.1 (interface)
Enter router ID type {default,interface,address}(address)
Enter router ID [158.101.112.113]: 158.101.112.111
