Will sharply 'pulling up' the MED on a rear-facing peer clear the wedgie, or make it worse??? Sorry, couldn't resist...

A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-grow-bgp-wedgies-03.txt Technical Summary 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, and that 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". Working Group Summary The Grow Working Group came to consensus on this document. Protocol Quality This document was reviewed for the IESG by David Kessens. -- "Fergie", a.k.a.
