Simulating Frame-relay

[mhostbaek]

Hello,

I would like to become better at configuring frame-relay on cisco routers, however I have no frame-relay wan connection to use.. I was wondering if it is possible to simulate frame-relay from one router, and then configure it on the other.. kinda like in a back-to-back environment.

If it is possible, what would I need - and where could I find more information about this topic.

Many thanks in advance,

I think you need at least 3 routers to get the purpose, one router works as the frame-relay switch and the other two are connected with the frame-relay switch respectively. You need two serial ports on the switch.

On the switch, you need configure it as a real FR switch, something like this:

frame-relay switching

!

!

interface Serial0/0

no ip address

no ip directed-broadcast

encapsulation frame-relay

no ip mroute-cache

frame-relay intf-type dce

frame-relay route xyz interface Serial1/1 zyx

!

on the two routers, you can try to practice frame-relay by use frame-relay map command.

Hope that will give you some hint.
