At this time VIO doesn't support the import of existing NSX objects.
thanks robswell for your answer.
so in our case , how can we refer the pre-existing DLR in VIO ? in order to attach the created VXLAN to the DLR through VIO ?
as DLR is the equivalent of the Neutron Router in Openstack , i was thinking to create the neutron router in VIO , but how can we link this router to the exiting DLR ?
Thanks for your support
You can't refer to the pre-existing DLR in VIO, you have to build a DLR via VIO - a Neutron router can be instantiated as a DLR. You can "link" the two routers via static routes over the router uplinks if you would like. I recommend reviewing the NSX-v Network Topologies and NSX-T Network Topologies guides, they provide an excellent overview of what is and is not possible in VIO from a networking perspective.
