2. Configure ADSL Router A (PPPoA client):
# Create a VT interface, and enable IP address negotiation.
<RouterA> system-view
[RouterA] interface virtual-template 0
[RouterA-Virtual-Template0] ip address ppp-negotiate
[RouterA-Virtual-Template0] quit
# Create a PVC, and enable it to carry PPP.

[RouterA-ATM2/4/0-pvc-pppoa-0/60] quit
[RouterA-ATM2/4/0] quit
3. Configure ADSL Router B in the same way ADSL Router A is configured.
Verifying the configuration
Both ADSL Router A and ADSL Router B can ping Router C successfully.
PPPoEoA configuration example
Network requirements
As shown in Figure 49, the hosts in the two Ethernets are connected to the ATM network through ADSL
Router A and ADSL Router B. They communicate with Router C through DSLAM.
The IP addresses of the VT interfaces of Router C are 202.38.160.1 and 202.38.161.1.
The VPI/VCI values of two PVCs connecting Router C and DSLAM are 0/60 and 0/61, pointing to ADSL
Router A and ADSL Router B, respectively.
Both the WAN port of Router C and the DSL interfaces of the ADSL routers use PPPoEoA. PPP
authentication is not performed. The IP addresses of the two ADSL routers are assigned by Router C.
