To ensure that traffic is distributed to the other physical connection when one physical connection fails, you must configure health checks for VBRs.
- Log on to the Express Connect console.
- In the left-side navigation pane, choose .
- Locate the target peering connection and click .
- Click Configure and then configure the health check based on the following information.
Configuration Description Source IP Any idle private IP address in the VPC. Destination IP The interface IP address of the network device of the on-premises data center.
If you need to perform an ICMP health check from your on-premises data center to the VPC to check if the connection is normal, we recommend that you set the Destination IP as the source IP address used for health checks of the VPC, and configure a route that points to this address.
