Frame-relay Simulations


I have a basic question on testing frame-relay on 2 cisco routers.

One router is a 2610 with a Wic2t, one 2504 router with 2 serial connections.

Is it possible to simulate a 2 frame-relay connections with both serial ports to the wic2t?

Thanks in advance for your input.

Re: Frame-relay Simulations

Your topology would look something like this.

2610 ---s0---------s0 2504


The problem with this configuration is when you configure ip address on the DTE equipment(say 2504), s0 and s1 of 2504 cannot fall in the same subnet. As long as u dont use layer 3 you can simulate frame-relay switching.

You will also need a special cable with smartserial interface on 2610 end, and a db60 interface on 2504 end.

To configure FR switching, see the following link.

To simulate FR and to facilitate L3 routing, you will need to have a 3rd router.

Re: Frame-relay Simulations


I will look into the PDF file for the config info.

The cables that I would need are, Smart Serial to DB60 male. Which cables are these, cisco part number and model number.

I have looked at the cisco documentation, but not able to figure out which ones they are. Can someone help to clarify the exact cable.

Thanks in advance,
