Abstract:The interactions between the IGP and BGP routing protocols which are running inside an ISP's network are sometimes hard to understand. The problem becomes particularly complex when there are dozens of routers/links and several thousands of destination prefixes. In this paper, we present a publicly available routing solver to evaluate routing what-if scenarios. The solver is able to model the complete network of an ISP and given the external routes learned by this ISP, to compute the paths towards all the desti… Show more
