Be careful of the IP Route command on a Switch

Well I decided to tear down my current voice lab and rebuild it as i work my way through the "IP Telephony Using CallManager Express Lab Portfolio" workbook. One of the labs I was working on required me to create RoAS (Router on A Stick) and I had everything configured and for some strange reason I couldn't ping between the other VLAN'S. This was due to having the ip route command configure by accident on my switch. I'll be honest and admit that I'm not quite sure how this effects routing quite yet, if you know feel free to leave a comment.

A colleague at my current job ran into the exact issue as he was making some IP address range changes on one of our remote sites. He was lucky and was able to have someone on site connect a console cable for him to connect back to the switch to remove the command. While all the devices stayed up he lost connectivity to the switch completely.

In other news I FINALLY scheduled my CCNA:Voice test for January 4th! I really need to pass on the first go round as the cut off date for IIUC is Febuary 28th and then it switches to the ICOMM series.
