Putting BGP on the Right Path: Better Performance via Next-Hop Routing
... ASes base routing decisions on the sequence of ASes along a path. To avoid the “count-to-infinity” problems that plagued earlier distance-vector protocols, BGP is a path-vector protocol that includes the AS-PATH attribute in each route announcement. This allows an AS to quickly detect and avoid path ...
