Hmm, a very good point. The actual problem is that it doesn't
seem to start advertising the less preferred routes if the other
edge router loses it's connectivity (actually: goes down).
I'm probably searching the wrong haystack here...

Yes, they are - however, both of the edge routers
are physically connected via point-to-point links to the
actual backbone. That shouldn't matter, though...
Thanks,
