Griffin and Geoff Huston}, title = {{BGP Wedgies}}, pagetotal = 10, year = 2005, month = nov, abstract = {It has commonly been assumed that the Border Gateway Protocol (BGP) is a tool for distributing reachability information in a manner that creates forwarding paths in a deterministic manner. In this memo we will describe a class of BGP configurations for which there is more than one potential outcome, and where forwarding states other than the intended state are equally stable. Also, the stable state where BGP converges may be selected by BGP in a non-deterministic manner. These stable, but unintended, BGP states are termed here "BGP Wedgies". This memo provides information for the Internet community.}, }
