Configuring PPPoA

When two routers are connected by using DSL interfaces through a dial-up connection, configure them as a PPPoA server and client. The PPPoA server acts as the PPP server, and you must configure an address pool for it to assign an IP address to the remote node. The PPPoA client acts as the PPP client, and you must configure address negotiation on it to accept the IP address assigned by the server end. For more information, see "Configuring PPP and MP."

Perform this task to enable a PVC or PVC group to carry PPP and configure a PPP mapping for the PVC or PVC group.

To configure PPPoA:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Create a VT interface.

interface virtual-template vt-number

N/A

3. Configure PPP authentication and IP address. For the PPP server, configure an address pool to assign an IP address to the remote node. For the PPP client, configure address negotiation to accept the IP address assigned by the server end.

For more information, see "Configuring PPP and MP."

Configure PPP authentication and IP address on the VT interface instead of an ATM interface. The IP address configuration does not take effect on ATM interfaces.

When you configure a static route for the VT interface, specify the next hop instead of the output interface. If you have to specify an output interface, make sure the physical interface bound to the VT is valid to ensure correct packet transmission.

4. Return to system view.

quit

N/A

5. Enter ATM interface view or ATM subinterface view.

interface atm { interface-number | interface-number.subnumber }

N/A

6. Enter PVC view or PVC group view.

  • Enter PVC view:pvc { pvc-name [ vpi/vci ] | vpi/vci }

  • Enter PVC group view:pvc-group group-number

N/A

7. Configure a PPPoA mapping.

map ppp virtual-template vt-number

By default, no mappings exist.
