A YANG Data Model for Traffic Engineering Tunnels and Interfaces
draft-ietf-teas-yang-te-15
Abstract
This document defines a YANG data model for the configuration and
management of Traffic Engineering (TE) interfaces, tunnels and Label
Switched Paths (LSPs). The model is divided into YANG modules that
classify data into generic, device-specific, technology agnostic, and
technology-specific elements. The model also includes module(s) that
contain reusable TE data types and data groupings.
This model covers data for configuration, operational state, remote
procedural calls, and event notifications.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
