By default, the preference for OSPFv3 internal routes is 10, and that for OSPFv3 external routes is 150.
The smaller the value is, the higher the preference is.
A router may run multiple routing protocols. Each protocol has a preference. When several routing
protocols find multiple routes to the same destination, the route found by the protocol with the highest
preference is selected.
