ATM is growing in popularity as a wide-area network (WAN) medium. ATM offers small cell size and strict quality of service, allowing voice, video, and data to coexist.
The following defines the terminology used in this configuration:
VPI – Virtural Path Identifier, 5 in this example
VCI – Virtual Circuit Identifier, 200 in this example
VC – Virtual Circuit
In this example, the ATM interface is atm0/0, and the IP addressing on the VC is 192.168.0.0/30.
Connect to the router. Enter the appropriate passwords. Then proceed as follows:
Enter configuration mode:
Enter interface configuration:
Enable the interface:
Create the subinterface:
interface atm0/0.200 point-to-point
Configure the local IP address:
ip address 192.168.0.1 255.255.255.252
Configure the VC:
Configure the protocols on this VC:
protocol ip 192.168.0.2 broadcast
Configure the encapsulation:
These steps complete the configuration.
