  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.
