IPoEoA configuration example
Network requirements
As shown in
ADSL Router A and ADSL Router B. They communicate with Router C through DSLAM.
The IP address of the VE interface of Router C is 202.38.160.1.
The VPI/VCI values of the two PVCs connecting Router C and DSLAM are 0/60 and 0/61, pointing to
Router A and Router B, respectively.
Both the WAN port of Router C and the DSL interfaces of the ADSL routers use IPoEoA.
