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 AN/ANH or ARN router.

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.

For example, in Figure 1-2, the AN/ANH or ARN 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.
