Hi Benoit,

Currently we know that the model maps correctly to a BGP PE-Based VPN, but not sure that it fills any VPN scenario like (CE to CE … ).
When we discussed at the beginning, we agreed to start with this VPN model and then see how it maps to others.

Best Regards,

Dear authors,

Thanks for posting draft-ietf-l3sm-l3vpn-service-model.
From the abstract, I see:

This document defines a YANG data model that can be used to deliver a

Layer 3 Provider Provisioned VPN service.  The document is limited to

the BGP PE-based VPNs as described in RFC4110<> and RFC4364<>.
I wonder:  What is specific to BGP PE-based VPNs in this YANG model?
From the L3SM charter, "Instead it contains the characteristics of the service, as discussed between the operators and their customers."
"Do you want a BGP PE-based VPNs", is this a typical question that operators ask to the customers?

Regards, Benoit
