CCIE Security Lab - checking IOS version

Unanswered Question
Feb 7th, 2008

Hi there,

In the CCIE Security Lab blueprint v2 say that the routes will have,

"Cisco IOS Software Version 12.2T Enterprise/IPSec/FW/IDS feature set is used on all routers" and "Cisco 3700 Series Routers". I have a Cisco 3725 and I can NOT download a 12.2T with that features any more from for this router.

Anyone know if 12.3T can be ok?



I have this problem too.

If you can't get 12.2T, you should get 12.3 mainline.

c3725-jk9o3s-mz.123-25.bin should be what you need.

That's is NOT correct.

Try to get the 12.2T if you can because if Cisco stated that it is the image that will be

tested in the lab, then you should use that

IOS version for your practice lab as well.

There are differences between 12.2T and 12.3 mainline. I will give you an example, in

12.2T IOS code, you do not have "ip eigrp next-hop" command while this command exists

in 12.3 mainline.

that's not good.... I'm trying to use this IOS to practice the lab but the cisco website doesn't allow me to download a 12.2T (any flavour) for any a Cisco 3725. How we are going to study something that we can use? Anyone know if there is another way to access old/deferral IOS from cisco website/ftp?

Cool, Thanks a lot for the link. Go back to 12.3T then.

did you mean 12.3 mainline? (hopefully)

"candidates studying for the CCIE Security lab exam will need to download IOS 12.3 mainline"

I've had to open a TAC case to get that IOS image for a 3600 from Cisco in the past. It's the only way to get it (or know someone who has it!)


(please rate the post if this helps!)

right. i wouldn't know

anything about getting the ios for

personal use.

I bet though you could

dig up anything on the net,


how it's made everything easily

available. you

really just have to know where

everything is.
