Hope someone can help. I am setting up a lab with three Cisco 2500 routers.I am using DCE DTE crossover cables between the routers. On one link I am getting Serial interface up down. I have checked the keep alive settings are both interfaces are set to 10 sec and encapsulation settings are both set to HDLC. I have the clock rate configured on the DCE end (whch is where I get the up down)and I have changed the crossover cable and still no joy. Any ideas?
