Use of Provider Edge to Provider Edge (PE-PE) Generic Routing Encapsulation (GRE) or IP in BGP/MPLS IP Virtual Private Networks
draft-ietf-l3vpn-gre-ip-2547-05
Technical Summary
This document describes a variation of BGP/MPLS IP Virtual Private
Networks (VPNs) in which the outermost MPLS label of a VPN packet
(the tunnel label) is replaced with either IP or a Generic Routing
Encapsulation (GRE). This enables the VPN packets to be carried over
non-MPLS networks.
Working Group Summary
There was concensus in the WG for this document.
Protocol Quality
This document has been reviewed for the IESG by Thomas Narten and Mark
Townsley
IESG Note:
This document proposes an automated mechanism for establishing tunnels
between provider-edge routers in a VPN but does not provide an
automated mechanism for establishing security associations for these
tunnels. Without such a mechanism, this document is not appropriate for
publication on the Internet standards track.
