    Last updated: 2024-01-13 16:40:45
      After an Internet tunnel is created, you can modify or delete it, edit tags, and perform other operations on the console.

      Prerequisites

      You have applied for an Internet tunnel as instructed in Creating an Internet Tunnel.

      Modifying a Tunnel

      Tunnel 1.0

      Contact your Direct Connect representative to modify a 1.0 Internet tunnel.

      Tunnel 2.0

      Perform the following operations to modify a 2.0 Internet tunnel.
      1. Log in to the Direct Connect console and click Internet Tunnels on the left sidebar.
      2. Locate the Internet tunnel to be modified, and click Change Tunnel under the Operation column.
      3. Select the Cloudification Link tab and configure as follows:
      Modify the tunnel configuration

      3.1.2 Modify Tencent Cloud primary IP, Tencent Cloud secondary IP, CPE peer IP, or VLAN ID, and choose whether to enable IPv6 as needed, and click Save.
      Note:
      IPv6 cannot be disabled once enabled.
      Modify the routing mode
      3.1.1 Click Edit on the right of the Routing Mode to modify the route. For BGP, modify BGP ASN and BGP key.
      Field
      Description
      BGP ASN

      The new tunnel configuration will take effect in several minutes depending on the network.

      Deleting an Internet Tunnel
