Try configuring the VL from R1 to R5, not R2 to R5.

Hello

Network Setup:
        R6
         |
R1--R2--------R5----R3

R2, R6, R5 are in Area 51, connected with ethernet, same subnet, R5 is an
ABR.
R3 is in Area0, Link between R5 and R3 is FR.
R1 is in area 2, R1 to R2 is HDLC link.
A Virtual Link from R2 to R5.

R6 has a few loopbacks, advertise this with ospf
R5 do summarization of this loopback networks. Goal: R3 should see only the
summary.

As long as I have no VL, the summarization works perfect, that mean R3 sees
only the summary route from the loopbacks.
But when I configure a VL between R2 and R5, then I get on R3 the summary
route AND all loopback routes!

Why this behavior?

thanks for any help
Oliver
