IOS 12.4 no longer supports IPSEC 3DES w/ 64 MB DRAM?

Unanswered Question
Feb 28th, 2007

I haven't gotten the whole process figured out, but it seems like I am out of luck...

I currently have some 2621xm routers with this IOS image:


It is the feature set for IP Plus IPSEC 3DES. I use this for connecting to the router via SSH. I would like to upgrade to 12.4 something, but it seems like everything requires 128 MB of DRAM.

Am I looking at things wrong? Any help is greatly appreciated!

I have this problem too.

Thanks for the information. I finally found out from Cisco that the 12.3(22) IOS only requires 64 MB DRAM, not the 96 that is posted on the website.
