Hmm... I was entering the config for my frame-relay switch, and started getting this error;
'route command not allowed between two DTE interfaces'
Which was particularly annoying, as I only had a single DTE interface connected (still waiting on my remaining DB60-DB60 cables to arrive..)
A quick google led me to a forum which stated you must enter the following command;
'frame-relay intf-type dce'
For each interface on your frame-relay switch..
This command was accepted fine. What I failed to do (facepalm!) was to then re-add the route commands that had previously been rejected, so I spent a good 10-15 minutes troubleshooting why my circuit would not come up.. Once the routes were re-added, everything went swimmingly!
