Q: If I want to, can I configure R2 without subinterfaces?
A: No. The question says you must use subinterfaces on R2.
Q: Can I disable inverse ARP but still have other PVCs on my map?
A: You might need to perform some other procedures to have only the PVCs you want on your Frame Relay map.
Q: Do I need to be able to ping my own router interface?
A: No. You are expected to ping across the Frame Relay cloud.
Q: I think I am having a problem on my Frame Relay switch. I have my configuration right and I am still not able to ping between R2 and R1, but between R2 and R5 is just fine. Could you please take a look in my Frame Relay switch?
A: Sure, I will verify the switch, but please double-check your configuration and make sure you are not missing anything or you are not mismatching anything.
