The following description of the characteristics of multi-instance CE is ?

  1. Since the MCE device is already bound to the VPN, there is no need to bind the VPN on the PE connected to the MCE device
  2. The MCE device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the route forwarding table of the corresponding VP.
  3. MCE is implemented by creating their own routing forwarding tables for different VPNs on the MCE device and binding to the corresponding interface o
  4. Configuring MCE enables a CE to connect to multiple VPNs at the same time, which can
    not only completely isolate the service between different VPN users, but also reduce the input cost of network equipment.
