Ballot Text

Technical Summary

   An IGP Flexible Algorithm (Flex-Algorithm) allows IGPs to compute
   constraint-based paths.  The base IGP Flex-Algorithm specification
   describes how it is used with Segment Routing (SR) data planes - SR
   MPLS and SRv6.

   This document extends IGP Flex-Algorithm, so that it can be used with
   regular IPv4 and IPv6 forwarding.

Working Group Summary

   From the shepherd writeup:
   We had a great discussion of the use cases and terminology and, as a result, 
   there will be changes in the version submitted for publication. One individual
   WG member strongly suggested a solution that wouldn't interoperate with routers
   not supporting Flex Algo. However, it is not uncommon for this WG member to be
   in the minority. 

Document Quality

   From the shepherd writeup:
   Cisco IOS-XR has an implementation that is shipping for IS-IS. Juniper
   has an implementation that has not yet shipped. 

Personnel

   The Document Shepherd for this document is Acee Lindem. The Responsible
   Area Director is John Scudder.
