A collection of OpenConfig and Cisco IOS XR examples

The goal of this repo is to provide a set of examples that illustrate how to program network elements using OpenConfig and gRPC. We will leverage different Open Source projects:

• Go as the main programming language.
• xrgrpc (gRPC library for Cisco IOS XR) to interact with IOS XR via gRPC.
• ygot (YANG Go Tools) to generate the OpenConfig data structures required for the gRPC calls.

Examples

Interface Configuration

• OpenConfig interface

Telemetry Stream Configuration

• OpenConfig telemetry

BGP Neighbor Configuration

• OpenConfig Network Instance: BGP

Configuring and Validating a BGP Peer session

The objective is to configure an interface (link) and bring up a BGP session, while setting up a BGP Neighbor Telemetry stream to track the current state of the BGP Finite State Machine. Check out the code here

Steps

1. Configure a Streaming Telemetry subscription using ygot and xrgrpc.

2. Configure the Peer link (interface) using ygot and xrgrpc.

3. Configure a BGP neighbor using ygot and xrgrpc.

4. Subscribe to a Telemetry stream to learn about BGP Neighbor status with xrgrpc.
