These Ansible roles set up servers running various Linux distributions to participate in BGP routing. Device and IP address data are pulled from NetBox. A separate VRF mgmt is configured for a L2 management interface.

Setup

Each server should have the following information recorded in NetBox:

• network interfaces mgmt*: used for management (Ansible) access; must define MAC and IP address
• network interfaces lan*: used for BGP routing; must define MAC address
• network interface lo: must define the IP address to announce over BGP, also serves as router ID

For the management IP address, another address in the same prefix should be defined with the tag gateway.

Run

Create a read-only token in NetBox. Define required variables:

# one for nb_inventory and one for nb_lookup
export NETBOX_API_KEY=<token>
export NETBOX_TOKEN="${NETBOX_API_KEY}"
# one for both
export NETBOX_API=<netbox API endpoint>

Run one-off tasks with (add --key-file or other options as necessary):

ansible -i inventory.yml -m ping 'server-*'

Run a playbook with:

ansible-playbook setup.yml -i inventory.yml -l 'server-*'
