What to find in this repo:

Network automation content with Ansible, Jinja, YAML, Python and Travis CI.

For a DCI demo using EVPN-VXLAN.
With network devices running Junos. Accross 2 differents DC.

The setup is already up and running. So this automation content is not used to build the setup.
This automation content is used to update the existing setup managing (stitching/unstitching/configuring/auditing ...) vlans to the DCI configuration. It uses a declarative approach and enforces the desired state against the network.

This repo covers also how to generate YAML variables (ready to be consumed by Jinja and Ansible) from a CSV file (source-controlled) using Python.

It has also a Python script to locate a mac address (i.e that connects to all the devices to provide the interfaces associated with a learned MAC addresses). This script uses the Ansible inventory file to get the list of devices ip address.

Repo content

Topology:

There are 2 DC (DC1 and DC2).

Dori, Superfast, Theia and Nori are QFX10000 devices.
QFX21, QFX22, QFX23, QFX24, QFX6 and QFX11 are QFX5100 devices.

EVPN-VXLAN runs on the QFX10k devices.
L3 is done on the QFX10k devices.
DCI (EVPN-VXLAN) is done on the QFX10000 devices.

QFX21, QFX22, QFX23, QFX24, QFX6 and QFX11 do L2 only.
QFX21 and 22 use MC-LAG. QFX23 and 24 use MC-LAG.
QFX6 uses a LAG. QFX11 uses a LAG.

Repo structure

ansible playbooks are at the root of the repository.
- pb.renderxxx.yml playbooks render templates. They dont connect to junos devices
- pb.rollback.yml playbook performs a rollback on junos devices.
- pb.addvlans.yml playbook configures the devices with new vlans
- pb.removevlans.yml playbook removes existing vlans from devices
- pb.check.vlans.yml playbook checks if vlans are presents from devices operationnal states
- pb.check.bgp.yml playbook checks if BGP sessions are established
- pb.replacevlans.yml playbook enforces the desired state on the devices (which is the best approach vs using pb.addvlans.yml + pb.removevlans.yml)
- pb.get.junos.facts.yml playbook gets the junos facts from the devices
ansible inventory file is hosts file at the root of the repository.
ansible configuration file is ansible.cfg at the root of the repository.
jinja templates are j2 files in the directory templates.
- 10kxxx.j2 templates in the directory templates are QFX10k specifics templates to:
  - add new vlans: 10kaddvlans.j2
  - remove existing vlans: 10kremovevlans.j2
  - replace actual vlans configuration with the desirated state: 10kreplacevlans.j2
- 5kxxx.j2 templates in the directory templates are QFX5k specifics templates to:
  - add new vlans: 5kaddvlans.j2
  - remove existing vlans: 5kremovevlans.j2
  - replace actual vlans configuration with the desirated state: 5kreplacevlans.j2
variables are yml files under group_vars and host_vars directories.
- host specific variables are yml files under the directory host_vars.
- group related variables are yml files under the directory group_vars
- generate_yml_vars.py generates yaml variables for Ansible from the CSV file.
templates are rendered into the directory render
Junos configuration files are saved automatically before any change into the directory backup
Junos configuration diffs from rollbacks done with ansible are in the directory rollback
Python scripts are at the root of the repository
- findmac.py locates a mac address accross the network.
- generate_yml_vars.py generates yaml variables for Ansible from the CSV file.
a CSV file at the root of the repository
The CI configuration files .travis.yml and requirements.txt at the root of this repository

Continuous integration with Travis CI

The Ansible playbooks and Python scripts in this repository are tested automatically by Travis CI.
Travis CI is notified by github at each git push and pull request events. This triggers new builds.
The files .travis.yml and requirements.txt at the root of this repository are used for this.
For ansible playbooks that doesnt interact with Junos devices, they are executed. If there is a syntax error, Travis will fail the build.
The command ansible-playbook has a built in option to check only the playbook's syntax (--syntax-check). This is how Travis is testing the playbooks that interact with Junos. Travis CI doesnt actually connect to the devices. If there is a syntax error, Travis will fail the build.
The same logic is applied to the python scripts.

The last build status is:

enforce the desired state against the network (best approach, declarative approach):

Ansible will enforce the desired state against the network:

desired states will be added on the network devices if they dont already exist
non desired states will be removed from the network devices if they exist

execute this playbook in dry-run mode to know what changes would happens on one specific device:

This is a dry-run so the device configuration doesnt change.

additionnal playbooks (not ideal as more imperative approach)

execute this playbook if you want to remove vlans:

ansible-playbook pb.check.vlans.yml
ansible-playbook pb.removevlans.yml 
ls backup

execute this playbook if you want to add vlans:

ansible-playbook pb.addvlans.yml
ls backup
ansible-playbook pb.check.vlans.yml
