Dedicated tunnels are network linkage segmentation of a connection. You can create dedicated tunnels that connect to different Direct Connect gateways to enable communication between your local IDC and multiple VPCs.
A new dedicated tunnel no longer supports the shared connection feature since August 1, 2020 00:00:00. However, you can continue using this feature on existing dedicated tunnels. If you delete the tunnel, you cannot apply for a new one with the shared connection after August 1, 2020 00:00:00.
To ensure the fine-grained scheduling capability of your network, do not publish the following routes: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 preceding extensive routes as follows for distribution:
|Name||Enter the name of your dedicated tunnel.||-|
||If you want to use Shared Connection, take notice of the background, select Shared Connection in the Basic Configuration tab, and enter Provider Account ID and Shared Connection ID.|
|Access Network||VPC, BM Network, and CCN are supported.||With CCN, you can connect to multiple VPCs through one dedicated tunnel.|
|VPC/BM Network||Select the ID of the network to which the dedicated tunnel will connect.||Currently, BM network only supports standard Direct Connect gateways.|
|Gateway Region||For CCN, gateway region is the CCN Direct Connect gateway region, which is the same as the public cloud region to which the connection access point belongs.||For shared connection, you need to ask the connection owner for information on the region of the connection access point.|
|Direct Connect Gateway||VPC Direct Connect gateway and the VPC are in the same region. CCN Direct Connect gateway and the connection access point are in the same public cloud region.||Currently, CCN Direct Connect gateways do not support the NAT feature.|
|VLAN ID||VLAN ID = 0: the connection does not enable subinterface and only one dedicated tunnel can be created.||To enable a MSTP connection to pass through multiple VLANs, you need to enable the Trunk mode for your ISP line.|
|Bandwidth||Bandwidth indicates the maximum rate, which can be changed later in "Change Tunnel". In the monthly 95th percentile billing mode, this parameter does not represent the billable bandwidth.||-|
|Peer IP||This IP can be user-defined or randomly assigned by Tencent Cloud. After submitting a ticket for tunnel creation, you can go to the details page of the tunnel to get the peer IP.
||If you choose to publish the peer IP to Direct Connect gateway, plan your IPs in advance to avoid any IP conflicts.|
|Routing Mode||BGP and static routes are supported.||Tencent Cloud ASN: 45090|
|BGP ASN||For BGP, this parameter is optional. Enter the AS number of the BGP neighbor on the CPE side, otherwise a random one will be assigned.||-|
|BGP Key||For BGP, this parameter is optional. Enter the MD5 of the BGP neighbor. The default value is “tencent". If this parameter is left empty, it indicates that no BGP key is required.||-|
|CPE IP Range||For Static, enter the IP range of the user-side CPE. Note that it cannot be conflict with the VPC IP range for non-NAT Direct Connect gateway||You can update the IP range later in the "Change Tunnel" page on the console.|
A dedicated channel may have the following status:
