Subject: [Idr] BGP-LS Flex Algo Extensions draft submitted to catch up with LSR work

Hello IDR WG,

We've posted a "routine" BGP-LS draft that includes extensions for
conveying some of the more recent Flex Algo IGP extensions defined by
the LSR WG into BGP-LS.

https://datatracker.ietf.org/doc/draft-hegdearavind-idr-bgp-ls-flex-algo-ext/

These are extensions beyond the base Flex Algo spec which was covered
by the BGP-LS RFC9351

This document catches up with the following LSR WG documents:
- IP Flex Algo: https://datatracker.ietf.org/doc/rfc9502/
- https://datatracker.ietf.org/doc/draft-ietf-lsr-flex-algo-bw-con/
- https://datatracker.ietf.org/doc/draft-ietf-lsr-igp-flex-algo-reverse-affinity/

Request the WG to review and provide feedback/comments. Also including LSR WG.

Given that these are straightforward BGP-LS extensions that are
aligned with and in continuation of RFC9552 and RFC9351, we would like
to ask for IDR WG adoption. We can also present this during the IDR
session at IETF 121 if required and if time allows.

Thanks,
Ketan (on behalf of all co-authors)

Abstract:

   Flexible Algorithm is a solution that allows some routing protocols
   (e.g., OSPF and IS-IS) to compute paths over a network based on user-
   defined (and hence, flexible) constraints and metrics.  The
   computation is performed by routers participating in the specific
   network in a distributed manner using a Flexible Algorithm
   Definition.  This Definition is provisioned on one or more routers
   and propagated through the network by OSPF and IS-IS flooding.

   BGP Link-State (BGP-LS) enables the collection of various topology
   information from the network.  BGP-LS supports the advertisement of
   Flexible Algorithm Definition and other Flexible Algorithm related
   advertisements as a part of the topology information from the
   network.  This document specifies the advertisement of further
   Flexible Algorithm related extensions in BGP-LS.
