For ECS details in this example, see Table 7. Parent topic: Using an Enterprise Router to Enable Communications Between VPCs in the Same Region
Configuring Kernel Parameters and Routes for ECS 3 Scenarios ECS 3 has two NICs, eth0 and eth1. You need to configure kernel parameters and add routes for ECS 3 to allow communications between eth0 and eth1. ECS 3 runs CentOS 8.0 64-bit.
ECS 3: a custom route for routing traffic from a VPC subnet to ECS 3. For details, see Table 4.
For details about resource planning of ECS 1 and ECS 2, see Table 11. Two NICs need to be installed on ECS 3. For details about resource planning of ECS 3, see Table 12. After ECS 3 is created, go to the ECS 3 details page.
Procedure Create two VPCs in region A and an ECS in each VPC. For details, see Creating a VPC. For details, see Purchasing a Custom ECS. For details about VPC and subnet planning, see Table 7. For details about ECS planning, see Table 8. Parent topic: Creating Resources
Procedure Create four VPCs in region A and an ECS in each VPC. For details, see Creating a VPC. For details, see Purchasing a Custom ECS. For details about VPC and subnet planning, see Table 9. For details about ECS planning, see Table 10. Parent topic: Creating Resources
For details about ECS planning, see Table 9. Parent topic: Creating Resources
Create an ECS in the service VPC. In this example, the ECS is used to verify the communications between the VPC and the on-premises data center. The ECS quantity and configuration are for reference only. For details, see Purchasing a Custom ECS.
Step 4: Verify the Network Connectivity Over the Direct Connect Connection Log in to the ECS and run the ping command to verify the network connectivity over the Direct Connect connection.

Hybrid cloud network Setting Up a Hybrid Cloud Network Using Enterprise Router and Direct Connect (Virtual Gateway) Enterprise Router Direct Connect (virtual gateway) VPC ECS There are two VPCs in a region.
Create an ECS in each VPC for verifying communications. For ECS resource details, see Table 5. For details, see Purchasing a Custom ECS. Log in to each ECS and take the following steps to verify the network connectivity: Multiple methods are available for logging in to an ECS.
Run the following command on the ECS: ping IP address of the ECS If you log in to ecs-demo-01 to verify the connectivity between vpc-demo-01 and vpc-demo-02, run the following command: ping 10.1.1.105 If information similar to the following is displayed, the two VPCs can communicate
Create an ECS in the subnet of the service VPC. Create a central network. When creating the central network, create a policy and add the enterprise routers in different regions to the policy.
Verify whether the VPCs are isolated from each other. ping IP address of the ECS To verify whether vpc-isolation-01 is isolated from vpc-isolation-02 and vpc-isolation-03, log in to ecs-isolation-01 and run the following commands: ping 10.2.0.215 ping 10.3.0.14 If information similar
To verify the network connectivity between vpc-demo-01 and vpc-demo-02, log in to ECS 1 (ecs-demo-01) and run the following command: ping IP address of ECS 2 (ecs-demo-02) Example command: ping 10.2.0.175 If information similar to the following is displayed, the two VPCs can communicate
