During test under bgp observed that

doing

Put
http://localhost:8181/restconf/config/bgp-linkstate-app-config:bgp-linkstate-app-config

<iana-linkstate-attribute-type xmlns="urn:opendaylight:params:xml:ns:yang:controller:bgp:linkstate-app-config">false</iana-linkstate-attribute-type>

Will behave as expected.

Then if we proceed to check the stored information

Get
http://localhost:8181/restconf/config/bgp-linkstate-app-config:bgp-linkstate-app-config

<errors xmlns="urn:ietf:params:xml:ns:yang:ietf-restconf">
<error>
<error-type>application</error-type>
<error-tag>data-missing</error-tag>
<error-message>Request could not be completed because the relevant data model content does not exist </error-message>
</error>
</errors>

Also if we try to do an update through

Post
http://localhost:8181/restconf/config/bgp-linkstate-app-config:bgp-linkstate-app-config

<iana-linkstate-attribute-type xmlns="urn:opendaylight:params:xml:ns:yang:controller:bgp:linkstate-app-config">true</iana-linkstate-attribute-type>

will end on
