Hi everyone. I was just given a project on standards and would like to implement the same IOS versions in my offices' routers and switches globally? How should I go about this, and what are tools that can be used for such purposes, while miniziming impact such as downtime, etc? How does your organizations achieve this, if this is already in place? What are the hurdles faced and what are the things that I should look out for?

    The biggest hurdle you'll face is that even if you use the same IOS level, the feature sets will be different for different devices. has details of how the IOS are packaged...

    If all your routers are of the same model then probably you wont have a problem
    And you'd just get the lasted release from Cisco

    However if your routers are different models
    Then although the IOS may run, but sometimes you'd face bugs
    i saw once an IOS giving problems when router is rebooted a command disappeared under the WAN interface.

    Theoretically it is best to have the IOS that is designed for the model

    My Organization go with the approach i told you about
    They check the router chassis, see the latest updates from cisco, test them and advise what best fits our requirements.
    So we dont standarize the IOS on our routers, each router model has a specific recommended IOS
    By the way, my company is a big one

    My enterprise pefrom audit of devices at install-time, and then upgrade to new versions on a single-instance basis; this way devices are not missed from the process or have incorrect image loaded.
