As shown in the following figure, each of the hosts in the two Ethernets is 
respectively connected to the ATM network through an ADSL Router, and they 
communicate with the router via DSLAM. The requirements are:

■

The IP address of the VE (Virtual Ethernet) interface of the router is 
202.38.160.1;

■

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

■

The DSL interfaces of the router's WAN port and ADSL Router all adopts 
IPoEoA.
