Explanation

VXLAN VNIs are virtual network identifiers that are used to identify and isolate Layer 2 segments in the overlay network. VXLAN VNIs have the following characteristics: VNIs can have over 16 million unique values. This is because VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard. This allows VXLAN to support a large number of Layer 2 segments and tenants in the network. VNIs identify a broadcast domain. This is because VXLAN VNIs are used to group the end hosts that belong to the same Layer 2 segment and can communicate with each other using VXLAN tunnels. The VXLAN tunnels are established using the VTEP information that is distributed by EVPN. The VTEPs are VXLAN tunnel endpoints that perform the VXLAN encapsulation and decapsulation. The VXLAN tunnels preserve the Layer 2 semantics and support the broadcast, unknown unicast, and multicast traffic within the same VNI.
