Hello again, I am running a Cisco 2621 router with iOS version 12.3(24) and I would like to set up SSH version 2, however, I see only version 1.5 is installed. Is SSH version 2, or 1.99 available on this version of iOS? I have googled and have not come up with a solid answer. Thanks so much!

SSH Version 2.0 (SSH v2) support was introduced in Cisco IOS platforms and images start in Cisco IOS Software Release 12.1(19)E.

Can you point me to a configuration guide for SSH version 2 please?

I have followed the setup procedure as described in the link, and have set up SSH 1.5 successfully, but it is only version 1.5. If I type:#ip ssh version 2, i get an error as follows:
router#enable
router#ip ssh version 2
^
% Invalid input detected at '^' marker.
What am I doing wrong?

carter(config)#ip ssh version 2
you must enter the conf t mode then config the SSH version

Tried that, this is what I am seeing:
gateway1#enable
gateway1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
gateway1(config)#ip ssh version 2

% Invalid input detected at '^' marker.

Secure Shell Version 2 Support (cisco.com)
Before configuring SSH, ensure that the required image is loaded on your device. The SSH server requires you to have a k9 (Triple Data Encryption Standard [3DES]) software image depending on your release.
