Frame relay gns

Hey Guys,

 I have 3 routers, (r1, r2, r3)

They all need to be connected to a frame relay router. Can that be done in gns? There is a frame relay switch.

Can someone please help with that.

You can do two things:

Use the built in frame-relay switch emulation, which I'm sure there are loads of guides of how to set up if you google it.

Or you could set up a router with enough serial interfaces to connect to all routers and do it "properly". I always use this way, so can't really help with the first.

So, to set up a router you need these commands:

frame-relay switching

int ser 0/0
encap frame
frame-relay intf-type dce
clock rate 64000
frame-relay route 122 interface Serial0/1 221

int ser 0/1
encap frame
frame-relay intf-type dce
clocl rate 64000
frame-relay route 221 interface Serial0/0 122

You can have many frame-relay routes pr interface, and if you do show frame-relay pvc on your connected router, you'll which ones are available. I use this all the time in GNS, works like a charm.

I am attaching the topology I have in gns. R4 is actually the ISP.

I need your help entering the DLCI's in the frame relay switch and how would they be connected.
Thanks
