Demo script

This demo script uses a docker images to streamline dependencies and make it easier to run on any system.

Build local docker image

A local image needs to be generated locally before running any other commands:

$ make build
docker build -f Dockerfile -t arista/avd-cvp-demo:latest .
Sending build context to Docker daemon  6.855MB
Step 1/12 : FROM python:3-alpine3.6
 ---> 37daba746bbe
Step 2/12 : LABEL maintainer="Arista Ansible Team <[email protected]>"
...

Power up devices.

Power up your devices what ever the solution is. You will see them in the undefined container

ZTP Registration

Check there is no container

Streaming Inventory

Check Configlets are not present

Configlets

Run Ansible playbook to rollout EVPN Fabric

A set of tags are available, but it is recommended to execute playbook in a row:

Playbook overview

Playbook: dc1-fabric-deploy-cvp.yml

Playbook manage following actions:

  • Generate Variables for CVP structure:
    • List of configlets
    • Containers topology
    • List of devices.
  • Collect CloudVision Facts
  • Deploy Configlet to CloudVision
  • Build Containers Topology
  • Configure devices with correct configlet and container.
  • Execute created tasks (wait 5 minutes while devices reboot)

Run Playbook

# Deploy EVPN/VXLAN Fabric
$make deploy
docker run -it --rm -v $(PWD):/project $(DOCKER_NAME):latest ansible-playbook ansible-playbook dc1-fabric-deploy-cvp.yml

Analyze result.

Once devices rebooted, you can review fabric status on devices themselfs or on on CloudVision as well.

Topology Update

Topology has been updated accordingly

Lab Topology

Configlet list

A set of new configlets have been configured on CloudVision and attached to devices

Lab Topology

Check device status

To validate deployment, connect to devices and issue some commands:

Revert topology

Once demo is over, you can revert to previous stage:

  • Reset devices to ZTP mode (Only devices part of the demo)
  • Remove configlet deployed previously
  • Remove dedicated container topology
  • Reboot devices

Playbook: dc1-fabric-reset-cvp.yml

# Reset EVPN/VXLAN Fabric tp ZTP
$ make reset
docker run -it --rm -v $(PWD):/project $(DOCKER_NAME):latest ansible-playbook ansible-playbook dc1-fabric-reset-cvp.yml
