I'm trying to connect two routers (7206 and 1700) via a serial interface over IP. Currently the serial communicates perfectly via IPX. I've just confgured ip addresses on both sides with a /30 mask and encapsulation is PPP but they cannot ping each other. I even tried HDLC but the IP stack on the interface cannot even open. I have attached the "show interface" command output of both routers:
