RE: Document Action: 'BGP Wedgies' to Informational RFC

  • From: Church, Chuck

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.
