What is the BFD version number supported by VRP?
- A. Version 1
- B. Version 2
- C. Version 3
- D. Version 4
Correct Answer: A 🗳️
VXLAN communication can be performed between different virtual machines by using a VTEP tunnel established by a vSwitch. Then, the communication process of VXLAN is:
1. The source WTEP encapsulates the ARP broadcast sent by the source VM into multicast packets and sends them to the L3 network.
2. After receiving the multicast packet, the destination VTEP learns the mapping between the source VM and the source VTEP and forwards the multicast packet to the local VM.
3. The local VM performs a unicast response.
4. The target VTEP encapsulates the Vxlan tunnel and establishes a mapping table encapsulation and sends the unicast to the source VTEP.
5. The source VTEP receives the mapping between the target VM and the target VTEP established by tunnel, and removes the tunnel and forwards it to the source VM.
6. The source VW communicates with the target VM through the tunnel for unicast packets.
- A. 1-3-2-4-6-5
- B. 3-5-2-4-1-3
- C. 1-5-6-4-3-2
- D. 1-2-3-4-5-6

- C. Create a DHCP server group first and add a DI-ICP server to the group.
- D. VLANIF 100 receives DHCP packets and forwards the packets to the external DHCP server through a relay agent.
