This tutorial is based on a the idea to combine many useful design concepts and patterns to address many challenges from device onboarding to the transition to LSA.
NOTE! The table is a summary of the concepts/patterns used and does not give a full explanation of the use-cases.
| Pattern | Description |
|---|---|
| Everything is a service | All configuration pushed to a device should be modelled as a service. Utilizes the CRUD functionality of NSO and the configuration gets an ownership. |
| One device per service (RFS) | Uniform design pattern suitable for both single node system and LSA setups. |
| Stacked services | CFS/RFS-layered services |
| Bundle device services | Services located per device (/nodes/router service). |
These are the implemented services and organized in the two tier stacked CFS/ RFS services.
CFS netinfra/router (s) netinfra/backbone-link (s) infra-internal/ibgp-fullmesh (s)

| Service/Layer | Description |
|---|---|
| CFS | The customer facing services |
| RFS | The resource facing services layer |
| /nodes/router | List enabling the one device per service concept. |
