You are implementing VXLAN broadcast domains in your data center environment. Which two statements are correct in this scenario? (Choose two.)

The fundamental operation of VXLAN is to extend Layer 2 segments over a Layer 3 network. The source VTEP (VXLAN Tunnel Endpoint) encapsulates the original Layer 2 Ethernet frame from a virtual or physical machine into a VXLAN header, which is then placed in a UDP/IP packet for transport. The VXLAN header contains a 24-bit VNI, but it does not contain a field for a VLAN ID. The original frame, including its VLAN tag (if present), is treated as the payload and is encapsulated in its entirety.

B. The VNI and VLAN ID are independent identifiers. While a VLAN is often mapped to a VNI, their numerical values do not need to match.

D. The VNI is a 24-bit value, which allows for up to 16,777,216 (2^24) unique segments, not a 16-bit value.

1. Juniper Networks Documentation, "Understanding VXLAN Encapsulation," EVPN Feature Guide. It states, "A VTEP encapsulates the Ethernet frame in a VXLAN, UDP, and IP header." and shows the packet format where the original L2 frame is the payload.

2. IETF RFC 7348, "Virtual eXtensible Local Area Network (VXLAN): A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks," Section 4, "Format of the VXLAN Header." This document defines the VNI as a 24-bit field and shows the encapsulation process where the "Inner MAC Frame" (the original L2 frame) is the payload.

3. Juniper Networks Documentation, "VXLAN Constraints on QFX Series and EX Series Switches," Feature Explorer. This document specifies, "VXLAN network identifier (VNI) — A 24-bit identifier that uniquely identifies a VXLAN."
