Introduction

This repo is based upon a simple NetDevOps demo to deploy SNMPv3 to a Spine and Leaf topology via Ansible. VIRL is also used to create a virtual test network to validate the changes.

VIRL

Topology files for test and prod are located within the virl dir.

.
└── virl
    ├── prod.virl
    └── test.virl

To create fake production network, using the following:

virl up -e prod -f virl/prod.virl

Jenkins

Job XML's are located within the jenkins folder for:

• Integration
• Delivery
• Deployment

Ansible

• SNMP configuration is defined within group_vars/all.yaml
• Hosts for the prod and test networks defined within inventory folder files.
• 2 playbooks included - deploy and test.
