Technical Summary

This  document presents two sets of paths for an address prefix
   that can be advertised by a BGP route reflector or confederation ASBR
   to eliminate the MED-induced route oscillations in a network.  The
   first set involves all the available paths, and would achieve the
   same routing consistency as the full IBGP mesh.  The second set,
   which is a subset of the first one, involves the neighbor-AS based
   Group Best Paths, and would be sufficient to eliminate the MED-
   induced route oscillations (subject to certain commonly adopted
   topological constrains).

Working Group Summary

Strong consensus.  Good discussion on the list.

Document Quality

Implemented in Juniper, Cisco 
RTG-DIR review: Tony Przygienda
This was discussed for over 5 years, and deployed. 
We are just slow in getting it standardized.
