Hi Anoop,

Latest IOS train is 12.4 train for 1720.No IOS yet for 2620 in 12.4 Please use IOS feature navigator to look for the memory and flash requirement depending on the IOS that you choose.

For 12.4 Train the IP feature set of 1720 require 48 MB memory and 16 MB flash. For the new IOS in 12.3 train for 2620 with IP plus feature set you need 64 MB DRAM and 32 MB flash.

Please see the feature navigator tool:
