Process of Connecting Multiple On-Premises Data Centers in the Same Region

Table 1 describes the overall process of using an enterprise router to connect on-premises data centers in the same region.

Table 1 Steps for connecting multiple on-premises data centers in the same region

Step

Description

Step 1: Create an Enterprise Router
  1. Create an enterprise router.

Step 2: Attach Global DC Gateways to the Enterprise Router
  1. Create Direct Connect connection DC-A and verify the connectivity.
    1. Create a Direct Connect connection to connect the on-premises data center to the cloud over a leased line provided by a carrier.
    2. Create a global DC gateway.
    3. Create a virtual interface to connect the global DC gateway to the connection.
    4. Attach the global DC gateway to the enterprise router and view the global DC gateway attachment in the attachment list of the enterprise router.
    5. Configure routes on the network device of the on-premises data center.
    6. Log in to the ECS and use ping to verify connectivity through the Direct Connect connection.
  2. Create Direct Connect connection DC-B and verify the connectivity by referring to 1.

Step 3: Verify Network Connectivity

Log in to a server in each of the on-premises data center and use ping to verify the network connectivity.
