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

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.
