A VPC-based direct connect gateway can be used to interconnect one Tencent Cloud VPC with one or more local IDCs. This document describes how to use a VPC-based direct connect gateway to build the Direct Connect network architecture that connects a VPC in Beijing to an IDC in Guangzhou.
The following figure shows you how to interconnect a Tencent Cloud VPC (
172.21.0.0/24) and a local IDC (
192.168.0.0/24) with a bandwidth of 2 Mbps.
Follow the steps below:
To create a connection, you need to first confirm the information and submit an application in the console, and then the carrier will start the engineering investigation and wiring. This process takes about 2-3 months. For more information, see Connection Overview. Perform the following steps to apply for a connection in the console.
|Connection Name||Enter a name for the connection, such as “Connection to Guangzhou IDC”.|
|Access Location||Select “ap-guangzhou-a-kyl” as an example. We recommend you first search for the access point and check its location, and then select the nearby access point.|
|Connection Provider||Select an eligible carrier, such as CTCC.|
|Cloud port||Ports in 1, 10, and 100 Gbps are available. To use a 100 Gbps port, please submit a ticket. Select 1 Gbps as an example.|
|Port type||Choose fiber optic port or electrical port as needed. The available ports vary with the port type. For example, 1 Gbps ports include fiber optic port and electrical port, while 10 Gbps ports only include fiber optic port. Select Fiber optic port as an example.|
|Bandwidth Cap||Select a desirable bandwidth.|
For more information on parameter configurations, see Applying for Connection
|Name||Enter a name for the direct connect gateway, such as “Beijing VPC - Guangzhou IDC”.|
|Associated Network||Select VPC.|
|Network||Select an existing VPC instance.|
|Gateway Type||Select Standard as an example.
|Name||Enter a name for the dedicated tunnel, such as “Beijing VPC - Guangzhou IDC”.|
|Connections||Select the connection created in Step 1.|
|Access Network||Select Virtual Private Cloud.|
|Virtual Private Cloud||Select an existing VPC instance.|
|Direct Connect Gateway||Select the direct connect gateway created in Step 2.|
For more information on the parameter configurations, see Creating a Dedicated Tunnel
|VLAN ID||A VLAN corresponds to a tunnel. Enter a value within the range of 0-3000. Entering 0 means one dedicated tunnel can be created. Enter “0” as an example.|
|Bandwidth||Specify the bandwidth cap of the dedicated tunnel, which cannot exceed the maximum bandwidth of the associated connection. Set it to “2 Mbps” as an example.|
|Tencent Cloud Primary IP||Enter the connection IP address on the Tencent Cloud side. Set it to “172.21.0.0/24” as an example.|
|Tencent Cloud Secondary IP||Enter the secondary IP address of the connection on the Tencent Cloud side. Set it to “172.21.0.2/24” as an example.|
|CPE Peer IP||Configure the connection IP address on the user (or carrier) side. Set it to “172.21.0.1/24” as an example.|
|Routing Mode||Select Static.|
|CPE IP Range||Enter “192.168.0.0/24” as an example.|
|CPE IP Range||Enter the customer IP range if Static is selected as the routing mode. This parameter cannot conflict with the VPC IP range in a non-NAT mode.|
To use a VPC-based direct connect gateway, configure a routing policy with direct connect gateway as the next hop and IDC IP range as the destination in the route table of the VPC subnet to enable communication.
After a connection and a dedicated tunnel are created, Cloud Monitor will automatically create a default alarm policy for each service. This default alarm policy does not configure recipient information, so you can only view alarms on the console. To configure a recipient, take the following steps.
|dc_band_rate||1 minute||>=||80%||Continuous 5 periods||Alarms every day|
