B. By modifying the OSPF cost values for the physical interface behind the two centers, you can influence spoke select different hubs to the network behind the center
C. Because there is only one virtual tunnel, it is not possible to implement a different hub by adjusting the OSPF cost of

Encryption, the center needs to decrypt the data transmission branch tunnel and re-encrypt the received data in the branch tunnel. Another case is that the two branches of communication are in the same city and the center is in another city, which introduces unnecessary latency. When the scale of the star IPSec network (hub-and-spoke) continues to expand, the configuration of the Traditional VPN becomes more complex and is not easy to maintain and tr
