OSPFv3 for IPv6 and Address Families

OSPFv3 Basic Configuration for IPv6 Link to heading

topology

NOTE:

router-id must be enabled. If the router ID is not configured, the router will dynamically choose an ID from the currently active IPv4 addresses (it will look for the Loopback and then other interfaces). If there is no active IPv4 address, the process will fail to start.
Link-local should be enabled in each interface in OSPFv3. If it is not configured, these routers will dynamically generate the link-local addresses as FE80::<MAC>
