Figure 3-1. Client and Server on the Same Physical Network
If, however, the client and the server are on different physical networks, a BOOTP
relay agent (also known as a BOOTP Gateway) must forward BOOTP packets to
their correct destinations. When you configure a Bay Networks router for BOOTP
services, the router acts as a BOOTP relay agent. F
igure 3-2 illustrates how
BOOTP works when the client and the server are on different physical networks.
