As shown above in the diagram the DHCP and Dataplane traffic are brought to the VM by VxLAN tunneling. Since it is just routed L3 traffic, DHCP traffic does not really require VxLAN. For sake of not having two different tunnel technologies we use VxLAN tunneling for both DHCP and Dataplane traffic. Now the question is if the OLT supports native VxLAN tunneling. In our case the OLT does not. Therefore some VxLAN tunnel encapsulation device is required (see transport middle boxes above). Those boxes are very simple to set up. See at the very end of this document how to build such a middle box.

- The IP of Edge SDN M&C in order to be accessed from SDN-C is currently hardcoded in the DG -> GENERIC-RESOURCE-API_bbs-internet-profile-network-topology-operation-common-huawei.json (<parameter name='prop.sdncRestApi.thirdpartySdnc.url' value='http://172.30.0.121:5000' />). The Edge SDN M&C external controller is not registered in ESR for this release. Note: The IP above is provided by Heat stack output, it is the Floating IP of the vBNG instance in Swisscoms Lab.
- To update the IP of Edge SDN M&C in the corresponding DG, one must export the relevant DG mentioned earlier, update the IP, import back and finally enable the DG.
