I am having a problem with setting up an X25 Lab. My problem is the VC will not establish. I am using 5 2500 routers, one of which is a 2521, which I want to use as the X25 switch. I have included the output from a debug x25 and also the config I am trying to use on the X25 switch and a config from one of the other routers. As I am new to X25 I would be very great full if someone could tell me what I am doing wrong or point me in the right direction, as I have spent hours trying to sort this out.
