Changing a Tunnel

Last updated: 2019-11-25 16:04:42

    Descriptions of Parameter Changes

    The following parameters can be changed for a dedicated tunnel:

    • IP address:
      Changing the IP address will interrupt the service.
    • BGP ASN:
      Changing the BGP ASN will interrupt the service.
    • Bandwidth:
      Changing the bandwidth will not interrupt the service, and the system will automatically overwrite the configuration.

      In the Shared Connection mode, you cannot apply for a bandwidth change for a dedicated tunnel; instead, such a change can only be applied for by the connection owner.

    • BGP KEY:
      Changing the BGP KEY will not interrupt the service, and the system will automatically overwrite the configuration.
    • User IDC IP range:
      The user IDC IP range can be modified, and the system will automatically distribute the configuration.

    After a tunnel change request is submitted, the system will complete the device configuration in a few minutes.

    Use Limits on Large IP Range

    In order to improve the fine-grained scheduling capabilities of your network, please avoid distributing the following routes:
    10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 100.64.0.0/10.
    You can split the above large routes into the following ones for distribution:

    • 10.0.0.0/8
      should be split into 10.0.0.0/9 + 10.128.0.0/9.
    • 172.16.0.0/12
      should be split into 172.16.0.0/13 + 172.24.0.0/13.
    • 192.168.0.0/16
      should be split into 192.168.0.0/17 + 192.168.128.0/17.
    • 100.64.0.0/10
      should be split into 100.64.0.0/11 + 100.96.0.0/11.
