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.
<Sysname> system-view
[Sysname] OSPFv3
[Sysname-OSPFv3-1] preference 150

The OSPFv3 process cannot run without a Router ID.
Make sure that different processes have different Router IDs.

By configuring different router IDs for different processes, you can run multiple OSPFv3 processes on
a router.
