configure ospfv3 routerid

configure ospfv3 routerid [automatic | router_identifier]


Configures the OSPFv3 router ID. If automatic is specified, the switch uses the highest IPv4 interface address as the OSPFv3 router ID.

Syntax Description

automatic Specifies to use automatic addressing.
router_identifier Specifies a router identifier, a four-byte, dotted decimal number.



Usage Guidelines

Each switch that is configured to run OSPFv3 must have a unique router ID. The router ID is a four-byte, dotted decimal number, like an IPv4 address. Even though the IP address format has changed from IPv4 to IPv6, the router ID format has not. It is recommended that you manually set the router ID of the switches participating in OSPFv3, instead of having the switch automatically choose its router ID based on the highest interface IPv4 address (if it exists). Not performing this configuration in larger, dynamic environments could result in an older link-state database remaining in use.

This command is accepted only when OSPFv3 is globally disabled.
