QuestionQ56

VXLAN

You are deploying VXLAN broadcast domains in a data center environment.

Which two statements are correct in this scenario?

Choose two
  • A The VNI is a 16-bit value and can range from 0 through 16,777,215.
  • B Layer 2 frames are encapsulated by the source VTEP.
  • C A VXLAN packet does not contain a VLAN ID.
  • D The VNI must match the VLAN tag to ensure that the remote VTEP can decapsulate VXLAN packets.
Explanation

A source VTEP encapsulates Layer 2 frames in VXLAN for transport across the Layer 3 underlay, and the destination VTEP decapsulates them. In standard VLAN-to-VNI forwarding, the inner packet does not carry the IEEE 802.1Q VLAN tag; the Layer 2 VNI in the VXLAN header represents the broadcast domain. The VNI is a 24-bit value and is locally mapped to a VLAN, so it need not numerically match the VLAN ID.
