You can configure the router to comply with the route selection rule defined in RFC 1583 or RFC 5340.
RFC 5340 and RFC 1583 define route selection rules differently. After enabling OSPFv3 on a device, you can configure the device to comply with route selection rules defined in either standard protocol as required. By default, a device complies with the route selection rules defined in RFC 5340. If you want the device to comply with the other protocol, you need to configure the device to comply with the rules defined in RFC 1583. Such configurations ensure that all OSPFv3-enabled devices in an AS comply with the same route selection rules defined in the same standard protocol.
