DUal 1700 router home lab question

Unanswered Question
Dec 8th, 2007

I have two 1700 routers. I was wondering if I can just hook the two 1700 routers directly to my laptop via a usb port and do some two router labs? I may need an adapter that connects the console cable to the usb port. Someone was telling me that I need to have two computers for this lab setup but I dont think so. A friend of mine said you can create loopback interfaces and he just used two routers and his laptop to get his CCNA. I just wanted to know what you think.

I have this problem too.

First, you will need a USB to serial adapter for your laptop so you can connect to the console ports on the routers. Here's one for $13:


Second, yes, you can connect the two 1700 routers together, but you want to do it via serial ports or ethernet ports. What model # of 1700 series do you have? What interface cards (WIC) do you have?

Thanks so much for your help. I have two 1720 routers. I do have them connected viaserial ports. I will get the adapter too. I will probably have to do my switching stuff on the routersim simulator for now.

Thanks again

you're welcome. don't forget to get the back to back serial cable for your 1720s. if they are wic-1ts, you will need DB60 to DB60. :)

good luck to you!

Thanks I checked it out and it was very helpful. I have had classes in the past but sometimes you forget all the info. I really appreciate everyones help. Took the test twice before first time 707 and second time 809. Time to hit it again after a few years away from it. Using the lammle book. I may do the two test route.

Appreciate the help guys
