Figure 58   PPPoA configuration networking diagram

1 Configure routers:

a Establish users for the PPP authentication and establish IP local address pool at 

the same time.

<3Com>system-view

[3Com]local-user user1 password simple pwd1

[3Com]local-user user2 password simple pwd2

[3Com]ip pool 1 202.38.162.1 202.38.162.100

b Establish the virtual-template (VT) interface, configure PAP authentication and 

IP address, and assign IP address from the IP address pool for the peer.

[3Com]interface virtual-template 10

[3Com-Virtual-Template10]ip address 202.38.160.1 255.255.255.0

[3Com-Virtual-Template10]ppp authentication-mode pap

[3Com-Virtual-Template10]remote-address pool 1

[3Com-Virtual-Template10]quit

[3Com]interface virtual-template 11

[3Com-Virtual-Template11]ip address 202.38.161.1 255.255.255.0

[3Com-Virtual-Template11]ppp authentication-mode pap

[3Com-Virtual-Template11]remote-address pool 1

[3Com-Virtual-Template11]quit

c Establish a PVC that is specified to bear PPP.

[3Com]interface atm 1/0/0.1

[3Com-atm1/0/0.1]pvc to_adsl_a 0/60

[3Com-atm-pvc-atm1/0/0.1-0/60-to_adsl_a]map ppp virtual-template 10

[3Com-atm-pvc-atm1/0/0.1-0/60-to_adsl_a]quit

[3Com-atm1/0/0.1]pvc to_adsl_b 0/61

[3Com-atm-pvc-atm1/0/0.1-0/61-to_adsl_b]map ppp virtual-template 11

As shown in the Figure 59, each host inside Ethernet dials into ATM network 
through an ADSL Router, and communicates with the router through DSLAM. The 
requirements are:

■

The Ip address of the router’s ATM subinterface is 202.38.160.1;
