Create an ECS in each verification subnet. Log in to the ECS and use ping to verify communications between the VPCs and enterprise router. Step 2: Create VPC Attachments and Add Routes Create VPC attachments to attach the three VPCs to the enterprise router.
Step 4: Verify Network Connectivity Log in to each ECS and use ping to verify connectivity. Parent topic: Setting Up a Hybrid Cloud Network Using Enterprise Router and Direct Connect Global DC Gateway
Configure kernel parameters and routes for ECS 3 to allow communications between NICs eth0 and eth1. 4 Verifying Network Connectivity and Traffic Scrubbing Log in to an ECS and run the ping command to verify the network connectivity.
Create an ECS in the VPC subnet that needs to communicate with the on-premises data center, log in to the ECS, and run the ping command. Delete the route and ECS used for verifying communications.

Log in to the ECS and run the ping command to verify connectivity. Establish connectivity using the other connection and verify connectivity.
Verify the network connectivity between VPCs. ping IP address of the ECS Use ECS-A as an example to verify the network connectivity between VPC-A and VPC-B: ping 192.168.0.5 If information similar to the following is displayed, the communications between VPC-A and VPC-B are normal
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Create an ECS in the subnet of the service VPC. Step 2: Attach the VPC to the Enterprise Router Attach the service VPC to the enterprise router.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Log in to the ECS and run the ping command to verify connectivity. Establish connectivity using the other connection and verify connectivity. For details, see 1.
