Supplying an OSPF ID
Each router configured with OSPF has an OSPF 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
Navigate to the global OSPF prompt and enter
router-id
ip_address
ip_address is a valid IP address in dotted-decimal notation.
