Network requirements
As shown in Figure 40, Router A, B, and C are connected to the ATM network for intercommunication.
The IP addresses of the ATM interfaces of the three routers are 202.38.160.1/24, 202.38.160.2/24, and
202.38.160.3/24.
In the ATM network, the VPIs/VCIs of Router A are 0/40 and 0/41, connected to Router B and Router C,
respectively. The VPIs/VCs of Router B are 0/50 and 0/51, connected to Router A and C, respectively.
The VPIs/VCIs of Router C are 0/60 and 0/61, connected to Router A and B, respectively.
All the PVCs on ATM interfaces of the three routers operate in IPoA application mode.

Configuration procedure
1. Configure Router A:
# Enter the view of interface ATM 2/4/0 and configure an IP address for it.
<RouterA> system-view
[RouterA] interface atm 2/4/0
[RouterA-ATM2/4/0] ip address 202.38.160.1 255.255.255.0
# Create PVCs and enable them to carry IP.
[RouterA-ATM2/4/0] pvc to_b 0/40
[RouterA-ATM2/4/0-pvc-to_b-0/40] map ip 202.38.160.2
[RouterA-ATM2/4/0-pvc-to_b-0/40] quit
[RouterA-ATM2/4/0] pvc to_c 0/41
[RouterA-ATM2/4/0-pvc-to_c-0/41] map ip 202.38.160.3
2. Configure Router B:
# Enter the view of interface ATM 2/4/0 and configure an IP address for it.
<RouterB> system-view
[RouterB] interface atm 2/4/0
