正確答案: A
問題6
Different virtual machines can use the VTEP tunnel established by vswitchi to communicate with VXLAN. Then the communication process of VXLAN is: 1 The source VTEP encapsulates the ARP broadcast sent by the source VM into a multicast packet and sends it to the L3 network. 2 After receiving the multicast packet, the destination VTEP learns the mapping relationship between the source VM and VTEP, and forwards the multicast packet to the local VM. 3 Local unicast response. 4 The destination VTEP encapsulates the Vxlan tunnel, establishes a mapping table and encapsulates it, and then unicasts it to the source VTEP. 5 The source VTEP receives the response and establishes the mapping relationship between the target VM and the target VEP, removes the tunnel and forwards it to the source VM. 6 The source VM and the target VM communicate unicast packets through the tunnel.
正確答案: C
