Solution Overview

When your on-premises network needs to communicate with a VPC, you can create a Direct Connect connection on the console to establish network connectivity between your premises and the cloud.

The telecom carrier needs to perform a site survey and lay the leased line, which takes about two or three months. Make sure that you arrange enough time for the project.

Process

Step	Description
Preparations	Before creating resources such as Direct Connect connections, sign up for a HUAWEI ID, enable cloud services, complete real-name authentication, top up your account, confirm the Direct Connect locations, confirm the port availability, complete the site survey, and confirm the prices.
Step 1: Create a Connection	Create a connection to reserve a dedicated port and work with the carrier to connect the leased line to the cloud. In this process, there are operations of the customer, carrier, and Huawei Cloud, and operation instructions for and the status of each phase will be displayed on the console.
Step 2: Create a Virtual Gateway	Create a virtual gateway and associate it with the VPC that you need to access.
Step 3: Create a Virtual Interface	After the connection and the gateway are ready, create a virtual interface so that your network can access the VPC.
Step 4: Configure Routes	After your on-premises network is connected to Huawei Cloud, configure routes on your on-premises network device.

The leased line construction process varies depending on the networking topology. The following figures show the logic of two common networking topologies. Consult your carrier for the actual networking topology.

Figure 1 shows the networking topology for establishing connectivity when your on-premises equipment room is in a different campus from that of the Direct Connect location.
