   This document shares experience gained from implementing algorithms
   to determine Loop-Free Alternates for multi-homed prefixes.  In
   particular, this document provides explicit inequalities that can be
   used to evaluate neighbors as a potential alternates for multi-homed
   prefixes.  It also provides detailed criteria for evaluating
   potential alternates for external prefixes advertised by OSPF ASBRs.
   This documents updates and expands some of the "Routing Aspects" as
   specified in Section 6 of [RFC 5286].
