In one example, a network management system (NMS) is configured to enable a target network device to support a particular network service based on service configuration information for the particular network service. The service configuration information may include information about nodes in a vendor neutral model that need to be added or modified in order to support the particular network service. The NMS determines similarity scores between nodes in a vendor neutral model and nodes in a target device specific model. Based on the similarity scores, the NMS generates a mapping from the vendor neutral model to the target device specific model. Using the mapping, the NMS may configure a target device to support the particular service.
