Azure SONiC DC Topology

Exploring the use of Ansible script to build a SONiC DC topology, demonstrated in this blog post Whilst there are Ansible collections aimed at configuring SONiC devices, this example uses a telnet connection.

Ideally, we'd boot strap the devices. Making them accessible to a management network, allowing the use of dellemc.enterprise_sonic. Utilising the collections greatly simplifies the deployment. dellemc.enterprise_sonic wasn't avaliable in 2020, when the deployment script was created.

Requirements

PIP Packages

• ansible
• gns3fy

Ansible Collections

• ansible.netcommon
• ansible.utils
• davidban77.gns3

These can be installed by running the following commands

python3 -m pip install -r requirements.txt
ansible-galaxy install -r requirements.yml
sed -i -e 's/#!\/usr\/bin\/env python/#!\/usr\/bin\/python/g' ~/.ansible/collections/ansible_collections/davidban77/gns3/plugins/modules/*.py

Deploying

Template(s) - WIP

Before the topology can be deployed, GNS3 needs to have the SONiC template imported. ansible-playbook setup-sonic-gns3-template.yml

DC Topology

Deploying the topology is as simple as running this command ansible-playbook deploy-sonic-dc-topology.yml
