Configuring a VXLAN Segment ID

In this recipe, we will configure a VXLAN segment ID. In a physical network with VLAN, a ID or VLAN ID is required for each VLAN segment. Similar to VLAN, VXLAN requires an ID for each VXLAN segment that will be used by NSX logical switches. The VXLAN segments are identified by a 24-bit VXLAN network identifier (VNI) or segment ID in VMware NSX. In this example, we will configure a segment ID range of 10,000-15,000 with an optional multicast IP address range of 239.1.0.1-239.1.63.254.

Getting ready

VMware NSX VNIs (segment IDs) are between 5,000-167,772,15. As per vSphere maximum configurations, the maximum static/dynamic port groups per vCenter is 10,000; therefore, up to 10,000 VNIs per NSX...
