Hi All,

This update of the draft is to get it ready for the WG to review towards WGLC .

The following is the high level overview of the changes:

1) Introduced Error Handling section where all these aspects have been consolidated.

2) Added the request for IANA registry for Color Extended Community reserved field. Changed the process to Specification Required and added DE guidelines since the flags and other space is too small for FCFS.

3) Added security consideration section.

4) Add the clarification for handling of route target during propagation as per the request and discussions on the mailer and also clarified the matching with BGP Router ID part.

5) Changed the segment type naming from numbers to alphabets to align with upcoming update in the draft-ietf-segment-routing-policy to remove confusion between the segment types and the protocol code-points as discussed on the Spring and IDR lists recently.

Besides this, there are other minor and editorial changes to prepare for WGLC.

We are also trying to capture all the implementation reports at the wiki below and would request WG members to help update the same as there are multiple shipping implementations of this specification:

https://trac.ietf.org/trac/idr/wiki/draft-ietf-idr-segment-routing-te-policy%20implementations%20

Also note that the draft is on IDR agenda for presentation on Thu in Singapore.

Thanks,
Ketan (on behalf of co-authors)

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Inter-Domain Routing WG of the IETF.

        Title           : Advertising Segment
    Routing Policies in BGP

Abstract:
   This document defines a new BGP SAFI with a new NLRI in order to
   advertise a candidate path of a Segment Routing (SR) Policy.  An SR
   Policy is a set of candidate paths, each consisting of one or more
   segment lists.  The headend of an SR Policy may learn multiple
   candidate paths for an SR Policy.  Candidate paths may be learned via
   a number of different mechanisms, e.g., CLI, NetConf, PCEP, or BGP.
   This document specifies the way in which BGP may be used to
   distribute SR Policy candidate paths.  New sub-TLVs for the Tunnel
   Encapsulation Attribute are defined for signaling information about
   these candidate paths.
