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

IP addresses.

Figure 1-2. Getting an Address from a PVC in Group Access Mode

The upstream router receives the requests on PVCs 31, 32, and 33,

respectively.

The upstream router refers to DLCI 31 in the BOOTP Client Interface

Table (Table 1-2

), finds the IP address (192.32.16.17) associated with the

DLCI, and sends a BOOTP response containing the IP address back to

PVC 31.

The upstream router does the same for the other two circuits.

Circuit containing three (3) PVCs

(DLCIs 31, 32, and 33 for virtual

connections to routers 1, 2, and 3)
