Planning a VXLAN configuration, includes the following steps:
Determine the virtual network topology in a physical network. For example, if you are hosting a service that consists of several VMs on different servers, you can assign a VXLAN segment for these VMs. The VMs in this VXLAN segment can communicate with each other but not with the other VMs that are not in this VXLAN segment.
Verify that the physical servers are connected through an IP interface and that IP multicasting is enabled on the physical network.
Create a numbering scheme for the VXLAN segments. For example, you can assign the VXLAN segments (VNIs) based on the application hosted by the VMs.
Create a VXLAN datalink by specifying the IP address and the VXLAN segment ID.
Optionally, you can assign the VXLAN segments with their own multicast address.
Create VNICs over VXLAN datalinks and assign the VNICs to zones.
Alternatively, you can assign the VXLAN links as the underlying link for the zone's anet link.
