In the IPSec active/standby link backup application scenario, gateway B uses IPSec tunneling technology and gateway A to establish an IPSec VPN.
In the active/standby mode of the USG dual-system hot standby, the service interface works at Layer 3, and the upstream and downstream routers are connected to the router. The administrator can view: USG_A status is HRP_M[USG_A], USG_B status is HRP_S[USG_B], current 15000+ session Table, every time a switchover occurs, all traffic is interrupted for a period of time, and seamless switching is impossible.
The following figure shows the data packet of the pre-shared key mode main mode exchange process in the first phase of IKE V1. What is captured below?
When the firewall works in the dual-system hot backup load balancing environment, if the upstream and downstream routers are working in the routing mode, you need to adjust the OSPF cost based on HRP.
The management control information and service information of the out-of-band management interface are sent on the same channel.
USG dual-machine hot standby must meet certain conditions and can be used below. What are the following statements correct?
The IPSec establishment of a device is unsuccessful. The debug print information is as follows. What are the possible causes of the fault?
? %%01IKE/4/WARING(1):phase2:proposal mismatch,please check ipsec proposal configuration 0 34476900 %%01IKE/7/DEBUG(d) dropped message from 3.3.3.1 due to notification type NO_PROPOSAL_CHOSEN
By default, GigabitEthernet0/0/0 can be used as an out-of-band management interface in the USG2200 series.
What type of message is the VRRP hello message?

In the IPSec VPN, the digital certificate is used for identity authentication. If the IKE main mode is used for negotiation, the certificate verification is completed in message 5 and message 6.
As shown in the figure, the Eth-trunk function is required to bind the interface. On this basis, if you need to implement the load balancing function of each interface, you need to add the following configuration command?
What are the scenarios in which the USG series firewall service port sends gratuitous ARPs when the following configurations are performed?
Which of the following protocols does the USG firewall hot standby not include?
Which of the following is not a message sent during ip-link detection?
An intranet has made a network, the old equipment is offline, the new network equipment is brought online, and after the service test, it is found that most of the original service traffic cannot work normally. What is the quickest way to restore the business?
