Deployment experience gained from implementing algorithms to
determine Loop-Free Alternates (LFAs) for multi-homed prefixes (MHPs)
has revealed some avenues for potential improvement.  This document
provides explicit inequalities that can be used to evaluate neighbors
as potential alternates for MHPs.  It also provides detailed criteria
for evaluating potential alternates for external prefixes advertised
by OSPF ASBRs.  This document updates Section 6 of RFC 5286 by
expanding some of the routing aspects.

This document is a product of the Routing Area Working Group Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.

This announcement is sent to the IETF-Announce and rfc-dist lists.
