Question
I have a simple hub and spoke topology set up with one hub and two spoke routers. I have set up eigrp AS and ip addresses correctly but cant route across the frame relay. However, my leased line point to point pings fine. This worked before but isnt working now. I can even see my eigrp neighbors. I need to find out whats wrong.
