Frame relay router

I had a thread here before about building a home-base lab. Someone had mention to get a 2521 router for Frame Relay switch.
I bought 3 of 2620 routers and 3 WIC-1T. I am planning to get a better router like XM and switches for my lab when I get some cash.

Anyways I should I get a 2521 router for my Frame relay or a NM-4A/S module for 1 of my 2620 router?

I was suppose to get the 2521, but the price is $100 including shipping/handling. And I stumble upon on NM-4A/S, and it looks like I can use it as frame relay(not sure). I am trying to save some money that is why I am looking at the NM-4A/S.

Any opinion on this?

I use a NM-4A/S as a frame relay switch and it works well.

I have a 2620xm with 4a/s and a 2611 with a 8a/s for use in frame relay.

Is it compatible with my 2620(regular)?

How's the performance between NM-4A/S vesus the 2521?

Are you going to put this in production or just deploy in a lab? If the latter, then it really doesn't matter, either option will perform the function you're looking for

It will be in my lab.

Thanks

Then you'll be fine going with the NM-4A/S, I use a 2620 with an NM-8A/S as the frame-relay switch in my lab

Ok thanks everyone

Same here

The 2620 and the 2621 have the same processor speed and if fitted with the same amount of DRAM will function identically. The only difference is the added FE port on the 2621, but if you are using it for a frame relay switch that wont matter. I use a 2650 with a NM-8a/s and it works great. I'm sure you'll be fine using one of your 2620's for it. How much DRAM are you running? If you're really low you might want to put in a little more, but it really doesnt take much to run a FR switch.

I'm using a 2520 that I got shipped on eBay for less than $40.

Doing all the Chris Bryant ICND2 Labs without any issues so far (Frame Relay - w/RIP2, OSPF and EIGRP on top).
