Right-on. We have fairly mature VR-based VPNs in our service provider customer networks. They still have among the fastest uptake with Enterprises willing to pay a premium for them in certain cases. The comments are in poor-taste, and not a realistic assessment of profitable service provider offerings. Rgds Shashi Kiran -----Original Message----- From: l3vpn-admin@ietf.org [mailto:l3vpn-admin@ietf.org] On Behalf Of Schliesser, Benson Sent: Thursday, February 05, 2004 9:49 AM To: erosen@cisco.com; Yakov Rekhter Cc: l3vpn@ietf.org Subject: RE: draft-ietf-l3vpn-gre-ip-2547-01.txt Being employed by a service provider that provides (a fair number of) VR-based VPNs, I'd say it's unfair to suggest "no one really cares about" them. If you'd like to argue that there are fewer VR-based VPNs than BGP/MPLS-based VPNs deployed in the world, then I won't oppose. (although my curiosity would like to see some evidence of this) But even that doesn't obviate the need for addressing the 'practical problems' of the VR model. I'd be thankful if Yakov would generalize the draft. And just because I can't help myself, I have to add (...not intended to reflect upon the BGP/MPLS versus VR models, nor start any religious wars therein, just to make the point that your analogy isn't entirely fair): You can't assume a steakhouse is unworthy of attention simply because vastly more people eat fast-food hamburgers. -Benson -----Original Message----- From: l3vpn-admin@ietf.org [mailto:l3vpn-admin@ietf.org] On Behalf Of Eric Rosen Sent: Thursday, February 05, 2004 10:25 AM To: Yakov Rekhter Cc: l3vpn@ietf.org Subject: Re: draft-ietf-l3vpn-gre-ip-2547-01.txt Eric> This document has been around a long time, and none of the folks Eric> who believe in VR-based VPNS (if there are even any still around) has Eric> bothered to contribute any text.

In your new role as chief advocate for VR-based VPNs? Or in your new role as ensurer of architectural and theoretical completeness? Wouldn't it be nice if we could keep a focus on practical problems and avoid debates about things that no one really cares about? After all, as someone once said, the proof of the pudding is in the eating, not in the debate about the pudding. :-)
