Configuring and Testing Network Connectivity Between an Edge Site and the Cloud

Scenarios

The edge AZ where an edge site resides connects to the central AZ on the cloud through two edge gateways and shares the same VPC with the central AZ, so that the edge site can access other cloud services on the cloud over a private network.

During the deployment of the edge site (hardware and software installation), the Huawei Cloud technical support team will connect the edge site to the central AZ in the associated Huawei Cloud region. You can create a VPC and two subnets on the VPC console, with one subnet in the central AZ and the other in the edge AZ. Then, test network connectivity by checking whether ECSs in the central AZ can communicate with ECSs in the edge AZ.

For the overall networking plan and requirements, see Overview and Networking Requirements.

Prerequisites

The edge site is in the Available state.

Creating a VPC

1. Log in to the management console.
2. Click in the upper left corner and select a region.
3. Click . In the service list displayed, choose Content Delivery & Edge Computing > CloudPond, or enter CloudPond in the search box.

   The dashboard is displayed.

4. In the left navigation pane, choose Edge Sites.
5. Click the name of the edge site for which you want to create a VPC.
6. In the Available Cloud Services area, locate Virtual Private Cloud and click Create.
7. On the Create VPC page, configure the parameters.
   • Select Edge for the subnet.
   • For details, see Creating a VPC.

8. Confirm the configuration and click Create Now.

Testing Network Connectivity

For the following steps, Windows ECSs are used to test the network connectivity.

1. Create an ECS named ECS01 in the central AZ, place it in VPC01, and select the default subnet (CIDR block: 10.0.1.0/24).

   Select Central AZ. For details, see Purchasing an ECS with Customized Configurations.

2. Locate ECS01 and record its private IP address (for example, 10.0.1.110).
3. Create an ECS named ECS03 in the edge AZ and place it in VPC01 (CIDR block: 10.0.3.0/24).

   Select Edge AZ. Configure other parameters as prompted.

4. Locate ECS03 and record its private IP address (for example, 10.0.3.110).
5. (Optional) If ECS01 and ECS03 are not in the same security group, add an inbound rule for each security group to allow access from each other.

   For details about to how to add security group rules, see Enabling ECSs in Different Security Groups to Communicate with Each Other.

6. Log in to ECS01 and ping ECS03.

   ping 10.0.3.110

   Check the command output. If the ECS can be pinged, the network connectivity has been established. If the ECS cannot be pinged, locate the cause and contact the Huawei Cloud O&M team.
