Do Huawei Cloud VPNs Have the DPD Function Enabled?

Updated on 2023-10-20 GMT+08:00

Yes.

By default, the dead peer detection (DPD) function is enabled for Huawei Cloud VPNs to detect the state of the IKE process in an on-premises data center.

After three consecutive detection failures, the IKE process in the on-premises data center is considered abnormal, and the tunnel on the cloud is automatically deleted.

The DPD protocol does not require that the peer end also be configured with DPD, but it requires that the peer end be able to respond to DPD detections. To ensure consistent tunnel states at the two ends, it is recommended that you enable DPD on your on-premises gateway to detect the IKE process state of the VPN service on Huawei Cloud.

NOTE:

Deleting the tunnel in the case of DPD detection failures will not affect service stability.
