When using VXLAN, what is the maximum number of unique virtual networks that can be created?

16 million
1 million
256 thousand
4 thousand

The correct answer is: 16 million

The maximum number of unique virtual networks that can be created using VXLAN (Virtual Extensible LAN) is indeed 16 million. This capability arises from the 24-bit segment identifier (VXLAN Network Identifier or VNI) that VXLAN uses to differentiate between virtual networks. In detail, the VNI allows for a range from 0 to 16,777,215, which totals 16,777,216 unique identifiers. This extensive address space enables a VXLAN implementation to support a vast number of isolated virtual networks, making it highly suitable for large-scale cloud environments where multitenancy and virtual network segmentation are crucial. Other options suggest significantly lower maximums, which do not align with the fundamental design of VXLAN technology. The vast number of unique identifiers provided by the 24-bit field is one of the primary advantages of VXLAN, allowing organizations to scale their networks efficiently without running into limitations that some other networking technologies may impose.
