IOS version

[neelima12]

Which is the best IOS version that I can upgrade my CISCO2911/K9 router to according to the Cisco best practices? Currently I have Version 15.0(1)M4, Version 15.2(4)M6, Version 15.2(4)M6a and Version 15.2(4)M2 on the routers. Will the latest IOS version mentioned in the Cisco downloads page be the best IOS version?

Hi there's 2 current recommended versions , the ones with the star for safe harbour are the recommended ios versions

try avoid going to the latest edition as you don't know what bugs exist in them yet
