Usage Guidelines

Usage Scenario

Generally, the device does not process PPPoE reply packets and directly forwards them to the PPPoE client. Only when the PPPoE client cannot identify PPPoE packets that the device directly forwards, the device needs to process the PPPoE reply packets sent by the PPPoE server to ensure communication between the PPPoE server and PPPoE client. The PPPoE reply packets are processed as follows:

When the policy for processing original fields in PPPoE packets is replace or keep:
- If fields are not contained in PPPoE reply packets sent by the PPPoE server, the device directly forwards PPPoE reply packets.
- If fields are contained in PPPoE reply packets sent by the PPPoE server and the format and content are consistent with those of the fields added to the user-side PPPoE packets, the device removes the original fields from PPPoE packets and forwards the packets. If the format and content are different from those of the fields added to the user-side PPPoE packets, the device directly forwards PPPoE reply packets.
When the policy for processing original fields in PPPoE packets is drop, the device directly forwards the PPPoE packets:

Precautions

The pppoe intermediate-agent information ignore-reply command takes effect only after PPPoE+ is enabled globally. To modify the configuration, disable PPPoE+ globally first.

If the device is configured to process the PPPoE reply packets sent by the PPPoE server, the user access rate is reduced when the PPPoE server sends a large number of PPPoE+ packets.
