Configuration This Container defines the configuration parameters related to NVO3. Chen, et al. Expires September 12, 2019 [Page 3] Internet-Draft NVO3 YANG March 2019 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. 5. States The operational states contains basic parameters associated with nvo3, such as parameters associated with nvo3-instance ,unicast- tunnel and multicast-tunnel. 6.
