Take a look at this.

Classical IP Over ATM Config Example

Objective:
=========

The Objective of this setup is to configure Classical IP Over ATM (RFC1577)
on a Cisco 7000 (SanFran) and on an LS1010. In this scenario the Cisco 7000
is the ARP server and also it is a Classical IP Over ATM Client. The LS1010
is only a Classical IP Over ATM Client.

Cisco7000 (SanFran) Config:
==========================

!
interface ATM2/0
 ip address 1.1.1.1 255.255.255.0
 ip route-cache same-interface
 atm esi-address 999999888888.00
 atm pvc 1 0 5 qsaal
 atm pvc 2 0 16 ilmi
 atm arp-server self
!

SanFran#sh atm arp-server

Note that a '*' next to an IP address indicates an active call

      IP Address TTL ATM Address
ATM2/0:
    * 1.1.1.1 18:08 4700918100000000613e5b5c0199999988888800
    * 1.1.1.5 18:50 4700918100000000613e5b5c0112345678912300

SanFran# ping 1.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
SanFran#ping 1.1.1.5

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 1.1.1.5, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/2/4 ms
SanFran#

LS1010 Config:
=============

!
interface ATM2/0/0
 ip address 1.1.1.5 255.255.255.0
 no keepalive
 atm esi-address 123456789123.00
 atm arp-server nsap 47.00918100000000613E5B5C01.999999888888.00
 atm maxvp-number 0
