I would like to create a lab to help with my certification studies. As part of my lab I have two Cisco routers (1841 and 2524 each with a 56k built-in WIC. I know frame-relay would be tough to emulate without a 3rd router to act as frame switch. However, I would like to bring up a simple HDLC or PPP PTP link. I configued each interface for the appropriate ip, encapsulation and set the clock rate to 56000. I have a crossover cat5 cable between them as the WICS have RJ-45 ports. However, I can't get the connection up. I don't even get a link light. I tried a st8 cat5 cable to no avail as well. How best can I get these two routers to bring up a WAN link (HDLC or PPP, doesn't matter). I mainly want to use it to study the routing protocols. What am I missing? I cam not even getting physical layer here.
I have this problem too.
