configure ospf routerid

configure ospf routerid [automatic | router-identifier]


Configures the OSPF router ID. If automatic is specified, the switch uses the highest IP interface address as the OSPF router ID.

Syntax Description

automatic Specifies to use automatic addressing.
router-identifier Specifies a router address.



Usage Guidelines

Each switch that is configured to run OSPF must have a unique router ID. It is recommended that you manually set the router ID of the switches participating in OSPF, instead of having the switch automatically choose its router ID based on the highest interface IP address. Not performing this configuration in larger, dynamic environments could result in an older link-state database remaining in use.



Do not set the router ID to


The following command sets the router ID:
