Configuring PPPoEoA
PPPoE adopts the Client/Server model. It encapsulates PPP packets into Ethernet frames and provides point-to-point connection on Ethernet. The following configurations enable the PVC to carry PPPoE and configure a PPPoE mapping for the PVC.
When you configure PPPoEoA, follow these guidelines:
When you configure a static route for a virtual-template interface, specify the next hop rather than the outgoing interface. If you want to specify the outgoing interface, make sure the physical interface bound to the virtual-template is valid to ensure correct transmission.
When multiple Layer 3 virtual Ethernet interfaces are connected through PVCs to a DHCP server that assigns IP addresses to the interfaces through static address binding, you must configure different MAC addresses for the interfaces with the mac-address command.
To configure PPPoEoA:
Step | Command | Remarks | |
|---|---|---|---|
1. Enter system view. | system-view | N/A | |
2. Create a VT interface. | interface virtual-template vt-number | Configure PPP authentication and an IP address on the VT interface (the IP address is invalid if configured on the ATM interface). | |
3. Set the PPP authentication mode and IP address; with the PPPoE server, an address pool should be configured to allocate IP address for the peer end; with the PPPoE client, address negotiation should be configured to accept the IP address allocated by the server end.. | See "Configuring PPP and MP." | N/A | |
4. Return to system view. | quit | N/A | |
5. Create a VE interface. | interface virtual-ethernet interface-number | N/A | |
6. Configure PPPoE parameters on VE interface (the configuration differs when with a PPPoE server and when with a PPPoE client). | See "Configuring PPPoE." | N/A | |
7. Return to system view. | quit | N/A | |
8. Enter ATM interface view. | interface atm { interface-number | interface-number.subnumber } | N/A | |
9. Enable packet padding on the ATM interface. | eoapad enable | Optional. | |
10. Create a PVC, and enter the PVC view. | pvc { pvc-name [ vpi/vci ] | vpi/vci } | N/A | |
11. Create a PPPoEoA mapping for the PVC. | map bridge virtual-ethernet interface-number | The interface-number argument refers to the VE interface created in the steps. | |
