YANG Data Model for L3VPN Service Delivery
Abstract
This document defines a YANG data model that can be used for
communication between customers and network operators and to deliver
a Layer 3 provider-provisioned VPN service. This document is limited
to BGP PE-based VPNs as described in RFCs 4026, 4110, and 4364. This
model is intended to be instantiated at the management system to
deliver the overall service. It is not a configuration model to be
used directly on network elements. This model provides an abstracted
view of the Layer 3 IP VPN service configuration components. It will
be up to the management system to take this model as input and use
specific configuration models to configure the different network
elements to deliver the service. How the configuration of network
elements is done is out of scope for this document.
This document obsoletes RFC 8049; it replaces the unimplementable
module in that RFC with a new module with the same name that is not
backward compatible. The changes are a series of small fixes to the
YANG module and some clarifications to the text.
