Which of the following statements about VXLAN is false?

A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra-subnet communication on the same VXLAN network.

Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
