■

The VPI/VCI addresses of two PVCs connecting routers with DSLAM are 0/60 
and 0/61, pointing to ADSL Router A and ADSL Router B respectively.

■

Both the router’s DSL interface employ PPPoEoA application mode. Each host 
within the two Ethernets will use pre-installed PPPoE Client program to make 
interactive PAP authentication with routers, and will obtain the IP address from 
the remote AAA server of the other side (not included in the following figure).
