Configuring PPPoA
When two routers are connected using DSL interfaces through a dial-up connection, configure them as PPPoA server and client, respectively. The two are different in that: with the PPPoA server, configure an address pool to allocate an IP address for the remote node; with the PPPoA client, configure address 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. | system-view | N/A |
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. | See "Configuring PPP and MP." | N/A |
4. Return to system view. | quit | N/A |
5. Enter ATM interface view. | interface atm { interface-number | interface-number.subnumber } | N/A |
6. Create a PVC and enter the PVC view. | pvc { pvc-name [ vpi/vci ] | vpi/vci } | N/A |
7. Configure a PPPoA mapping for the PVC. | map ppp virtual-template vt-number | N/A |
