3. Configuration
This Container defines the configuration parameters related to NVO3.
The configuration includes vxlan enable,geneve enable, parameters
associated with nvo3-instance, parameters associated with unicast-
tunnel and multicast-tunnel.
In this document, we contains two types of encapsulation:
GENEVE[I-D.ietf-nvo3-geneve]and VXLAN-GPE[I-D.ietf-nvo3-vxlan-gpe].
4. Control plane configuration
This Module will be defined in the next version.

Internet-Draft NVO3 YANG November 2018
5. States
The operational states contains basic parameters associated with
nvo3, such as parameters associated with nvo3-instance ,unicast-
tunnel and multicast-tunnel.
