. Introduction

The Interface to the Routing System (I2RS)

[

I-D.ietf-i2rs-architecture] provides read and write access to the

information and state within the routing process that exists inside

the routing elements, this is achieved via the protocol message

[

I-D.ietf-i2rs-rib-info-model].

Internet-Draft RIB DM November 2015

This document defines a YANG [

RIB that satisfies the RIB use cases and aligns with the RIB

information model.

1.1. Definitions and Acronyms

RIB: Routing Information Base

Information Model (IM): An abstract model of a conceptual domain,

independent of a specific implementation or data representation.

follows:

o Brackets "[" and "]" enclose list keys.

(read-write) and "ro" state data (read-only).

o Symbols after data node names: "?" means an optional node and "*"

shown.

2. Model Structure

The following figure shows an overview of structure tree of the ietf-

i2rs-rib module. To give a whole view of the structure tree, some

details of the tree are omitted. The relevant details are introduced

in the following sub-sections.
