Configuration procedure
1. Configure Router A:
# Enter the view of the ATM 1/0 interface and configure an IP address for it.
<RouterA> system-view
[RouterA] interface atm 1/0
[RouterA-Atm1/0] ip address 202.38.160.1 255.255.255.0
# Establish a PVC and enable it to carry IP.
[RouterA-Atm1/0] pvc to_b 0/40
[RouterA-atm-pvc-Atm1/0-0/40-to_b] map ip 202.38.160.2
[RouterA-atm-pvc-Atm1/0-0/40-to_b] quit
[RouterA-Atm1/0] pvc to_c 0/41
[RouterA-atm-pvc-Atm1/0-0/41-to_c] map ip 202.38.160.3
2. Configure Router B:
# Enter the view of the ATM 1/0 interface and configure an IP address for it.
<RouterB> system-view
[RouterB] interface atm 1/0
[RouterB-Atm1/0] ip address 202.38.160.2 255.255.255.0
# Establish a PVC and enable it to carry IP.
[RouterB-Atm1/0] pvc to_a 0/50
[RouterB-atm-pvc-Atm1/0-0/50-to_a] map ip 202.38.160.1
[RouterB-atm-pvc-Atm1/0-0/50-to_a] quit
[RouterB-Atm1/0] pvc to_c 0/51
[RouterB-atm-pvc-Atm1/0-0/51-to_c] map ip 202.38.160.3
3. Configure Router C:
# Enter the view of the ATM 1/0 interface and configure an IP address for it.
<RouterC> system-view
[RouterC] interface atm 1/0
[RouterC-Atm1/0] ip address 202.38.160.3 255.255.255.0
# Establish a PVC and enable it to carry IP.
[RouterC-Atm1/0] pvc to_a 0/60
[RouterC-atm-pvc-Atm1/0-0/60-to_a] map ip 202.38.160.1
[RouterC-atm-pvc-Atm1/0-0/60-to_a] quit
[RouterC-Atm1/0] pvc to_b 0/61
[RouterC-atm-pvc-Atm1/0-0/61-to_b] map ip 202.38.160.2
IPoEoA configuration example
Network requirements
As shown in Figure 68, each of the hosts in the two Ethernets is respectively connected to the ATM
network through an ADSL Router, and 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 value of 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 adopt IPoEoA.
