A YANG Data Model for Routing Management
draft-ietf-netmod-routing-cfg-15
Abstract
This document contains a specification of three YANG modules.
Together they form the core routing data model which serves as a
framework for configuring and managing a routing subsystem. It is
expected that these modules will be augmented by additional YANG
modules defining data models for individual routing protocols and
other related functions. The core routing data model provides common
building blocks for such extensions - routing instances, routes,
routing information bases (RIB), routing protocols and route filters.
