Abstract Abstract
This document contains a specification of three YANG modules and one This document contains a specification of three YANG modules and one
submodule. Together they form the core routing data model which submodule. Together they form the core routing data model which
serves as a framework for configuring and managing a routing serves as a framework for configuring and managing a routing
subsystem. It is expected that these modules will be augmented by subsystem. It is expected that these modules will be augmented by
additional YANG modules defining data models for control plane additional YANG modules defining data models for control plane
protocols, route filters and other functions. The core routing data protocols, route filters and other functions. The core routing data
model provides common building blocks for such extensions -- routes, model provides common building blocks for such extensions -- routes,
