Changing a Tunnel

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.
