preferred route statistics

[Frederik Kriewitz]

Hello,

I noticed that the preferred route counter seems to be incremented for
each time the route is exported by another protocol.
E.g. I've a static protocol with 25 routes which are exported by two
other protocols, this results in the following statistics:
25 imported, 0 exported, 50 preferred

I'm wondering if that's the intended behavior?

So far I expected that preferred means number of routes which are
considered "best" in the corresponding routing table (so preferred
would be always <= imported).

Best Regards,
Freddy
