How to simulate Frame Relay WAN connection between two Cisco routers

[dmariotti]

I would like to set up a lab environment to simulate

a WAN\Frame relay between two cisco routers. Any configurations of SO's

and cable types(crossover-null modem) would help greatly

Thank You in advance

Cisco routers can act as a frame-relay switch as well. So

Here is the best url which will help you for all your requirements like, cable required, config, verification and troubleshooting

To add to the other post, If you are falling short of interfaces, when the number of routers increases, you can use two or more routers as frame-relay switches and use tunnelling in between to switch the frames.

You can use the back to back cable (DB-60 to DB-60) to connect between the DTE routers and the Frame-relay switch. Preferably configure the frame-relay switch end with the DCE clock command. All other configurations are provided in the link that Tejal has provided.

Hope that helps.

Go to www.cisco.com

In the Search box, enter "frame relay back to back"

Select the first "hit"

Select the first TAC authored document on the list.

Exactly what you are looking for: two routers using frame relay between them with no switch or other equipment.

First requirement when learning Cisco routers is to learn to use www.cisco.com. It's not always this easy, the number of false hits to even a well crafted search can be discouraging, but learning to access information that is available is an essential skill.

Good luck and have fun!
