I have a 1751 with a Serial port configured with a Frame Relay connection to the Internet and an Ethernet port connected to our local network segments (Multiple) with subinterfaces. I can ping appropriately between each of the internal network segments just fine, but I am unable to ping the IP address that I have assigned to the Serial Port connected to the Frame Internet connection. The Serial port is currently not connected to the Internet as they've yet to turn up the circuit, but shouldn't I be able to ping the router's serial port IP address? Or is this normal? I'm concerned that it represents a larger issue that will become evident when I try to connect to the live circuit.
It's normal. You are not able to ping from the router to its own ip address which has the Frame Relay point-to-point connection even the line and protocol are all up. But if you have that IP address path in the routing table, you can ping it from the other routers, computers, switches etc., if the PVC is not active, you are not able to ping anymore.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
