There is no such thing as a well known large bgp community.

Hi Job/WG,

Reading the document I have a feeling/suggestion that perhaps this is a very good time now to define few IXP focused well known Large Communities such that most often signalled policies between RS and their clients are well defined and not random among IXPs. 

That may also in fact encourage faster migration to LCs from Extended Commuities. 

Thx a lot,
Robert

I reviewed the draft;

The Abstract and Introduction says, "It includes guidance for both the Internet Service Provider side peering with Route Servers and IXPs operating Route Servers."

However, the document no longer calls for any direct actions by ISPs. Obviously, the actions recommended for IXPs will impact the ISPs using IXPs. However, the statements above imply direct actions by ISPs in addition to IXPs, not indirect impacts on ISPs from IXP actions.

You should probably rephrase the above statements to refer to indirect impacts on ISPs unless you expect ISPs to take other direct actions, and if you do, those other actions need to be more clearly stated.

Thanks.

Abstract:

   This document outlines a recommendation to the Internet operational
   community to avoid the use of BGP Extended Communities at Internet
   Exchange Point (IXP) Route Servers.  It includes guidance for both
   the Internet Service Provider side peering with Route Servers and
   IXPs operating Route Servers.  This recommendation aims to help the
   global Internet routing system's performance and help protect Route
   Server participants against misconfigurations.
