The Virtual link I have is for an area 2 which is located off Router 5. It
doesn't affect the area 33 to area 0 route propagation. I think it might be
some kind of bug, or have something to do with R4 to R1 being a ptp
subinterface. Weird. Will play with it some more tomorrow. Thanks for the
replies....Bob
