3-36
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.
Examples
# Set a preference of 150 for OSPFv3 routes.
