Supplying an OSPF Router ID

Each router configured with OSPF has an OSPF router ID. This IP address

uniquely identifies this router in the OSPF domain.

By convention, and to ensure uniqueness, the router ID should be one of the

router’s IP interface addresses.

The router ID determines the designated router on a broadcast link if the priority

values of the routers being considered are equal. The higher the router ID, the

greater its priority.

If both OSPF and BGP are running on the router, the OSPF router ID must be

identical to the BGP identifier. In addition, the OSPF router ID must match one of

the IP addresses configured on the router.

By default, OSPF uses the IP address of the first OSPF circuit configured on this

router. You can use the BCC or Site Manager to specify an IP address.

Using the BCC

To change the OSPF router ID, navigate to the global OSPF prompt (for example,

box; ip; ospf

) and enter:

router-id

<ip_address>

ip_address

is a valid IP address in dotted-decimal notation.
