negotiation to accept the IP address allocated by the server end. For more information, see "Configuring
PPP and MP."
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.
The following configurations enable the PVC to carry PPP and configure a PPP mapping for the PVC.
To configure PPPoA:
Step Command Remarks
1. Enter system view.

2. Create a VT interface.
interface virtual-template
vt-number
Configure PPP authentication and
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 an IP address for the
remote end; with the PPPoE
client, address negotiation
should be configured to
accept the IP address
allocated by the server end.

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.
