QuestionQ45

VXLAN

Because of severe congestion, some VXLAN packets are being dropped.

Which two statements are correct?

Choose two
  • A The VXLAN has no retransmission capability.
  • B The EVPN congestion notifications should be used.
  • C The host endpoints determine when to retransmit any lost packets.
  • D The VXLAN acknowledgement packets would be used.
Explanation

VXLAN uses UDP encapsulation, and UDP provides no reliability or retransmission capability. VXLAN also defines no acknowledgement packets for loss recovery. When reliable delivery is needed, the transport protocol or application at the host endpoints detects loss and decides whether to retransmit; EVPN is a control-plane mechanism and does not provide VXLAN packet retransmission.
