Configuring Remote Access

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.
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.
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 for setting up routing paths
in Chapter 4.
