The question is: R1 has disabled inarp on s0/0.50 point-to-point what would be needed to ping R3. The answers: Frame map on R1, Frame map on R3, or nothing is required it would work. I chose nothing, since it is a point-to-point I thought that it will send all traffic on that DLCI. Thier answer is that it needs a frame map on R1. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
