Question 3

Which of the following statements are true about VXLAN concepts?

A : A VirtualIF interface is a Layer 3 logical interface created for a BD.

B : On a VXLAN network, VNIs can be mapped to BDs in 1:1 mode, and a BD can function as a VXLAN network entity to forward VXLAN data packets.

C : In a VXLAN packet, the source IP address is the local node ' s VTEP IP address, and the destination IP address is the remote node ' s VTEP IP address. This pair of VTEP IP addresses corresponds to a VXLAN tunnel.
