Connecting BayStack AN and ANH Systems to a Network

1-12

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.

6. The AN/ANH assigns the IP address and subnet mask to any synchronous

interface that receives a BOOTP response.

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
