Figure 1-1. Calculating an IP Address (Direct Access PVC or

Standard PPP)

-- A Frame Relay PVC in group access mode refers to its BootP client

interface table to find an associated IP address for the BayStack router.

For example, in Figure 1-2, the BayStack 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.

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

in Chapter 3.
