Lab 2: Provision POD2

Description

In this lab, we will use Arista Validated Design (AVD) to generate POD2 underlay and overlay configuration and CloudVision to deploy it. This time, eos_designs variables need to be created. At the end of this lab, POD1 and POD2 will be 2 separate EVPN domains: all leaf can only reach the Loopback0 of other leaves of their respective pods.

Instructions

  1. Go to the folder /home/coder/project/persist/avd-toi.

  2. Open inventory.yml and uncomment all lines in the file.

  3. Create group_vars/POD2.yml and fill it with required information.

    Use group_vars/POD1.yml as example.

    Use this documentation to know what to modify.

    Solution: Don't cheat, use your brain and RTFM One possible solution is accessible here.

  4. Run the playbook build.yml with the command ansible-playbook build.yml. Verify the configurations in intended/configs.

  5. Run the playbook deploy.yml with the command ansible-playbook deploy.yml.

  6. Go to the CloudVision instance or your Arista Test Drive lab and open the Provisioning menu.

  7. Go to the Tasks tab, select the tasks that have been created by the playbook and create a change control. At this point, you can select the Parallel arrangement to have the tasks executed in parallel within the change control.

  8. You will be taken to the Change Control tab in the newly created change control. You can rename the Change Control to give it a meaningful name. Review, Approve and Execute the change control.

  9. When the change control is completed, underlay and overlay of POD2 will be configured. You can eventually access the devices via SSH and run the show running-config command to verify the configuration.

  10. Connect to a spine and check the underlay and EVPN BGP sessions:
