Shepherd writeup

1. Summary

The document shepherd is Russ White. The responsible Area Director is Alvaro

This document documents the current implementation state for a set of
extensions to BGP so a BGP speaker can advertise multiple paths rather than
a single best path to peers. These additional paths are intended to used to
eliminate path oscillation, in a number of situations where advertising
multiple paths can improve network convergence, and in a number of
situations where BGP is used in "high fan out" equal cost multipath network
topologies to provide optimal path availability.

2. Review and Consensus

There has been no controversy over this document, which simply indicates how
many implementations of these extensions there are, and which specific
capabilities have been included in those implementations. The document shows
