How to simulate a WAN/Frame relay connection

[ciscorat]

I would like to set up a lab environment with a 3640 and 2513. I would to simulate a WAN connection between routers and am wondering how to config S0's and what type of cables do I need, also do I need CSU\DSU's being that this is a simulation.
Thank You in a advance!

Get a cable that has DCE on one side and DTE on the other and connect the serial ports together. You do not need a CSU/DSU.

On the DCE side use the clockrate command on the Serial interface.

If you want to simulate a frame-relay connection you will need a third router, that will act as a frame-relay cloud. Take a look at this example:

Yo ciscorat do this
Parts: 1 back to back cable (basically a serial cable that is crossed)
Personally I prefer the modular cables available from kg2.com. The are reconfigurable without plugging and unplugging from the serial ports of the router.
Well lets get started.
Most any cisco router hase the ability to simulate a frame-relay switch.
So pick the router that has the most serial ports and issue these commands

Frame-relay switching

interface Serial0
no ip address (ip address is optional on frame-relay interfaces)
encapsulation frame-relay
no fair-queue
clockrate 56000
frame-relay lmi-type cisco
frame-relay intf-type dce

Commands for non frame relay switch
encapsulation frame-relay
no ip address (apply an ip address if you prefer both ends)
no fair-queue
clockrate 56000
frame-relay lmi-type cisco
Wala you now have a point to point frame switch.
