IP feature set should be good enough.


Here's a GD code that you can use c2600-i-mz.12.2-40.

Access the software advisor tool on CCO at the following link and choose the option 'Find software with the features I need' and select IGRP and to find images that support IGRP.

I don't know what's the model of the 2600 you have. IGRP on 2611 is supported in 12.2(11)T7 or earlier versions. It appears you may have to downgrade the code to 12.2 or earlier version to enable IGRP. But, check the software advisor tool to pick the right image.


BTW, is there any specific reason why you want to run IGRP. You can consider EIGRP, successor to IGRP, and there are lot of similarities between them.

IGRP support was removed in 12.3T. You'll need to run an IOS 12.2 or earlier to use IGRP. Or better yet use EIGRP or the like.
