Generalizing Ring Convergence
Why is all this so important to understand? Because virtually every topology you can envision that has any sort of redundancy is, ultimately, made up of rings (full mesh designs are considered by many to be an exception, and Clos fabrics are exceptions). To put it another way, virtually every network topology in the world can be broken into some set of interconnected rings, and each of these rings is going to converge according to a very basic set of rules.
• Every ring has, for each destination, a set of links not used to forward traffic.
• The failure of any link or node on a ring will cause traffic to either be drop...
