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. Ethernet interfaces will discard PVC-carried Ethernet frames
smaller than 60 bytes. Therefore, you should pad these frames to 60 bytes on ATM interfaces.
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..

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 PPP and MP." 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. Create a PVC, and enter the
PVC view.
pvc { pvc-name [ vpi/vci ] |
vpi/vci }
N/A
10. 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.
