Is there a sample of a read operation with something equivalent to a pretty print of the configuration that has been read.
You can use the CRUD service in combination with the codec service to pprint the configuration you read. You can find an OC-BGP example using YDK 0.5.0 (or later ) at:
Down the road, you can expect the codec service to support other encodings (e.g. JSON, GPB, YAML, etc).
