% Unrecognized command

ROM: 1600 Software (C1600-BOOT-R), Version 11.1(10)AA, EARLY DEPLOYMENT RELEASE
Also can someone tell me what is the version 11.1 showing in this output of show version since correct me if I am wrong but I am running version 12.3 so IPv6 should be available right ?
sorry you are right its 12.2 but can someone explain why there is no ipv6 command available or at least direct me if I can use a simulation software like Packet tracer to make some practice with ipv6 thank you
look here: http://www.cisco.com/en/US/technologies/collateral/tk648/tk872/tk373/technologies_white_paper_09186a00802219bc_ps6553_Products_White_Paper.html you will find on what IOS version IPv6 is working.
Hi Andrea, I did some poking around with the Feature Navigator on Cisco's site and it looks like IPv6 is available only in the T (Technology) train for 12.2. The latest release is 12.2(15)T16. Try downloading that and loading it up on your 1600 and you should get the IPv6 commands. IPv6 is also available in 12.3 mainline if you want to use that.
The type of IOS image is usually as important as the version. The base image doesn't support IPv6 on most of the routers I have seen (even on version 12.4). You'll need to advanced IP services or higher, I think. That might require a flash memory upgrade, depending on your hardware.
