質問 6：
Which of the following about the characteristics of multi-instance CE is incorrect?
A. MCEThe device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the routing forwarding table of the corresponding VP.
B. configureMCE,A CE can be connected to multiple VPNs at the same time, which not only realizes complete isolation of services between different VPN users, but also reduces the investment cost of network equipment.
C. The implementation principle of MCE is to create its own routing and forwarding table for different VPNs on the MCE device and bind it to the corresponding interface.
