Lets say we have a 2600 series router on which Flash memory is having capacity of 16MB. The existing IOS image in the router having 10MB. If we want to upgrade a new IOS image (capacity of 12MB) then obviously we need to clear the existing image first to free up the same. Requesting if anyone can share the steps & commands need to execute this task succesfull.
