5.5 (Optional) Configuring the xPoA-xPoE Protocol
Conversion
Configuring protocol conversion is required only when the encapsulation mode is IPoA or
PPPoA; it is not required when the encapsulation mode is IPoE or PPPoE.
Context
In the xPoA access mode, data cannot be directly transmitted in the IP network, and protocol
conversion is required. IPoA data and PPPoA data can be transmitted in the IP network only
after the IPoA-IPoE and PPPoA-PPPoE conversions are performed.
The principle of the IPoA protocol is different from that of the PPPoA protocol. In the PPPoA
mode, the BRAS automatically allocates a gateway address to the PPPoA user after the PPPoA
user passes the authentication on the BRAS and dialup is successful. Therefore, the default
gateway address need not be configured in the PPPoA mode. IPoA data is forwarded according
to the route to the destination IP address and the next hop IP address needs to be configured.
Therefore, the default gateway address needs to be configured in the IPoA mode.
provides the configuration flow for the xPoA-xPoE protocol conversion.
