Hi newnetman,


Buy 2621 XM

The XM stands for extra memory. This is the correct one for CCIE lab.


Need any further help?

Ok sure.


1.2621 FE VPN

This suggests that the router is standard 2621 and not the XM version. The VPN could refer to two things:

a) There is VPN IOS sw pre-loaded

b) There is an HW based VPN AIM module installed. You don't need either for CCIE.


2.2621 XM <-- This device supports extra memory and therefore more will offer more features since it can hold a larger IOS image than non-XM routers. You will be tested on the additional feature that the standard 2621 will not support.


3.2621 WIC-1T

This simply would refer to 2621 standard with a WIC-1T card. We need XM so it's no good to be honest.


4.2621 w/NM

The 2600 series routers have 3module slots in the back as you may know. It has one NM module slot which is a fair bit larger than the other 2 WIC slots. So this description would translate to a standard 2621 router with some sort of NM module. For further information about NM modules please see the following link:

I must point out that some of these module options can be very expensive but equally others have very little value.


All the best,

Ajaz

Hi,


If you are considering buying on somewhere like eBay, the best bargains seem to be 2611XM. As far as I can see, the main difference between 2611XM and 2621XM is processor performance, which you normally don't really care about in the lab. Functionally they can do the same tricks.


The series without XM they tend to be cheaper but the memory is smaller. You can run 12.2T in a 2611 by jumping through some elaborate hoops, but they will never run 12.4.


There are models with one or with two ethernets, depending on the fourth digit. Thus, a 2610 has one ethernet, but a 2611 has two.


Final point: the XM series are all FastEthernet. For the non-XM series, the third digit tells you. So 2610 and 2611 are 10 Mbps, whereas 2620 and 2621 are FastEthernet 100 Mbps.
