 Description   

Hi Netconf-dev

When we have data model with leafs having default values.
For ex:
leaf ip-address

{ type string; default 127.0.0.1; }

I don’t see the ip-address value in my restconf response. Where when I check the dataobject, the object has the default value set.
How do I ensure the default value is set even in mdsal?

We are right now using Boron SR3.

The yang rfc: https://tools.ietf.org/html/rfc6020#section-7.6.1
states that when the leaf does not have a value and has a default value the server "MUST operationally behave as if the leaf was present in the data tree with the default value as its value."

It's not state anywhere that the default value has to be present in the datastore. I think the default value is only present in generated bindings and not NormalizedNodes which restconf uses.

This discussion should be aimed on mdsal since this is out of scope of restconf.
But i think that the mdsal team stated multiple times that the default values should NOT be present in the datastore.
