Re: [PWE3] IETF 58 Minutes

[Rahul Aggarwal <rahul@juniper.net>]

Hi Danny,

A few comments inline. Please look for ###

Rahul Aggarwal - Use of PE-PE IP/GRE/IPSec for MPLS PWs
http://www.ietf.org/internet-drafts/draft-raggarwa-pwe3-pw-over-ip-00.txt
This document describes procedures for carrying MPLS PWs over IP, GRE or
IPsec tunnels.  Still uses MPLS control plane.  Motivation is that there
may be non-MPLS routers between ingress and egress PEs.  MPLS packet gets
sent over an IP or GRE tunnel.  Can also use IPSEC to secure the tunnel

Rahul - asked to make a WG document
Eric Rosen - asked why this document exists since there is a similar
         document in MPLS WG
Rahul - Agreed that other documents exists.  This document does not define
any
        protocols - just procedures.

### I also said that the MPLS WG document specifies how to encpsulate MPLS
in IP/GRE. It does not specify how to carry PWs over IP/GRE. And that
there is an existing document for doing the same for 2547 over IP/GRE.

Mark Townsley - seconded Eric's opinion.  Said that this was a way to send
        MPLS over IP without using L2TPv3.
Rahul - said that there was a need coming from SPs

### I also said that this addresses the case when the PW control plane is MPLS and
backbone is IP only.

thanks,
rahul


Luca Martini - Said that it is contained in control document
Rahul - will follow up, but not sure that it is in control document
Luca - send me a paragraph
Andy Malis - add voice to the chorus.  All specified elsewhere
Kireeti Kompella - Document in L3VPN in GRE defined elsewhere. This is the
       moral equivalent for PWE3.  If already in place, perhaps we should
       just expand and clarify.
Yaakov Stein - For MPLS label handling is obvious.  For IP, not clear.
       Inner label may be OK.  Document raises a good point about how to
       handle labels over IP.
Rahul -  concurred.
Danny - take it to the mailing list.
