Hardware and Software Overview

1-11

a. A PVC in direct access mode or a Bay Networks Standard interface

calculates the IP address by adding 1 to the IP address of the interface that

received the request.

For example, in Figure 1-1 the upstream router’s interface address is

192.32.1.1. This means that the upstream router calculates 192.32.1.2 as

the booting router’s IP interface.

a Frame Relay PVC in Direct Access Mode

b. A PVC in group access mode references its BOOTP client interface table

to ﬁnd an associated IP address for the booting router.

Note: If the IP address plus 1 equals a broadcast address, the upstream router

calculates the IP address by subtracting 1. For example, if its interface is

7.255.255.254, the IP interface for the booting router is 7.255.255.253.
