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
inventoryfolder files. - 2 playbooks included - deploy and test.
