I have a test lab configured in gns3 for frame-relay, and I had the following question.
I configured frame relay on both router's physical interfaces, but I couldn't ping either one. I then changed the physical interface to only encapsulate frame-relay and then I created subinterfaces for point-to-point connections. I could then ping each router.
My question is, when is it appropriate to use the "frame-relay map ip" command? I tried this command on the physical interface before creating my subinterfaces and it didn't work.
