Configuration roadmap
The configuration roadmap is as follows:
1. Create the PVC of ATM interfaces on each router.
2. Specify the protocol to bear the IP protocol.
Data preparation
To configure IPoA, you need the following data:
z
The IP addresses of their ATM interfaces of the three routers are 202.38.160.1/24,
202.38.160.2/24 and 202.38.160.3/24 respectively.
z
In ATM network, the VPI/VCI of Router A is 0/40 and 0/41, connecting with Router B
and Router C respectively.
z
The VPI/VCI of Router B is 0/40 and 0/42, connecting with Router A and C respectively.
z
The VPI/VCI of Router C is 0/41 and 0/42, connecting with Router A and B respectively.
Configuration procedure
Step 1 Configure Router A.
# Enter the ATM interface view, and configure an IP address for it.
<RouterA> system-view
[RouterA] interface atm 1/0/0
[RouterA-Atm1/0/0] ip address 202.38.160.1 255.255.255.0
# Establish PVC to bear IP.
[RouterA-Atm1/0/0] pvc to_b 0/40
[RouterA-atm-pvc-Atm1/0/0-0/40-to_b] map ip 202.38.160.2
[RouterA-atm-pvc-Atm1/0/0-0/40-to_b] quit
[RouterA-Atm1/0/0] pvc to_c 0/41
