Each device in a LIS is configured with the ATM address of the ATM ARP server and acts as
an ARP client. When the ARP client starts up, it sends a request for a SVC over a well-known
VC using VCI 5. The ATM ARP server then establishes an SVC with the ARP client. The ATM
ARP server uses Inverse ARP to learn the IP and ATM addresses of the client and registers the
client. Figure 5-28 shows how the originating ARP client establishes a connection with the
destination ARP client.
