Understanding Route Redistribution

Free registration required

Executive Summary

Route Redistribution (RR) has become an integral part of IP network design as the result of a growing need for disseminating certain routes across routing protocol boundaries. While RR is widely used and resembles BGP in several nontrivial aspects, surprisingly, the safety of RR has not been systematically studied by the networking community. This paper presents the first analytical model for understanding the effect of RR on network wide routing dynamics and evaluating the safety of a specific RR configuration.
