For example, in Figure 1-2, an AN router sends BOOTP requests for its IP
address. The upstream router receives the request on PVC 31. The
upstream router determines the DLCI, refers to DLCI 31 in the BOOTP
client interface table, finds the IP address, and sends a BOOTP response
containing the IP address back to PVC 31.

5. The upstream router sends the IP address and subnet mask to the AN in
a BOOTP response message.
Note: The BOOTP client interface table contains a data link connection
identifier (DLCI) and IP address pair for each PVC. You use Site Manager to
create this table when you follow the instructions for setting up routing paths

Chapter 4.
