Re: [Idr] Multi Instance BGP

["UTTARO, JAMES" <[e-mail]>]

Robert,

                I see no mention of being able to assign different AS numbers to different instances.. At various times over the years I have identified the rationale for assigning different AS numbers based on AFI/SAFI on a given router. As an ex FlowSpec, L3VPN, L2VPN… on the same box may require a service provider to organize the AS numbering that is optimized for one of these but is problematic for others. This then requires AS manipulation on a per box basis which is undesirable.. Would it make sense to add this separation along with AFI/SAFI in this doc??

Thanks,
                Jim Uttaro

Subject: [Idr] Multi Instance BGP

Hello,

To meet the submission deadline I uploaded a below proposal for Multi Instance BGP.

Please do not hesitate to provide any comments on or off the list.

I consider it as first possible step to separate BGP-LS (or for that matter other non
routing related data) into independent BGP process primarily targeting to run
on the x86 general compute hardware without making any changes to BGP code
therefor making it 100% backwards compatible.

If there is need we could discuss it during the interim meeting, otherwise we could
just keep it for the list based comments.

Kind regards,
Robert

Abstract:
   As the number of operational use cases of BGP grows there is demand
   to increase the level of separation and processing independence
   between various address families carried by BGP today.  This document
   augments base BGP specification in allowing local configuration of
   BGP port number by the operator to run parallel fully disjoined BGP
   instances allowing full processing separation between them.

   While local BGP implementation may already assure BGP process or
   thread robustnes the general aim here is to allow similar level of
   groups of BGP address families independence when running BGP code on
   general purpose hardware as well as x86 based route reflectors..

Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org<https://urldefense.proofpoint.com/v2/url?u=http-3A__tools.ietf.org&d=DwMFaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=s7ZzB4JbPv3nYuoSx5Gy8Q&m=VlD88dkPqw1byyLEghLDS69vtpVXfXnfbzWwstsYYF4&s=kCiDrHZDlNSo-Ubre0dWwsF9rmliK94I7xr8BJu2iTg&e=>.
