Hi Oliver,
The reason you are getting the summary and the
more specific routes on R3 after you've configured
the virtual-link goes back to the basic concept.
A virtual-link is an extension of Area 0. You will
have to configure summarization on R2 in order
to remove the specific routes on R3. Just add the
Area 51 range XXXXX YYYYYY command on R2.
Best of luck.
Danny
