Abstract
Methods and apparatus to analyze autonomous system (AS) peering policies are disclosed. A disclosed example method comprises obtaining routing information from two or more border routers of a first AS, wherein the routing information identifies two or more routes to a prefix associated with a second AS, and wherein the second AS is a peer of the first AS, identifying one of the two or more routes as an inferior route advertised by the second AS based on the routing information, and determining whether a routing impact is present within the first AS due to the advertised inferior route.
