Figure 1-1. Getting an IP Address from a Bay Networks Standard Circuit or

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.

For example, in Figure 1-2, routers 1, 2, and 3 send BOOTP requests for

IP addresses.

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.

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 in Chapter 3.
