Usman, since an AS is defined as “A collection of prefixes with a common routing policy”, what would you use one for if not to connect to other autonomous systems? If you are connecting to a single other autonomous system, then, arguably it is impossible for your prefixes to have a distinct routing policy and you are, therefore, part of that other AS. If you are connecting to multiple other autonomous systems, then, you are, by definition multihomed. If you have some better way to manage this, I’m all ears. Owen
