We’ll identify the variables, build a Jinja2 template, then create a PyEZ application to take the input parameters from the user and deploy them to the router:
- Determine the variable components of our configuration task. They are summarized in the following list:
- Physical interface
- Logical unit identifier
- VLAN identifier
- Local interface IP address
- VRF identifier
- Route distinguisher (for MPLS VPN configuration)
- Route target community (for MPLS VPN configuration)
- Customer site router IP address
- Customer-located networks
- Reduce the variable components of the configuration into the most minimalist form by using derivations: deriving one value in the configuration from another input parameter. This brings simplicity through minimizing ...
