Dynamic Host Configuration Protocol (DHCP)
Overview

• the agreed-upon network address
• a default gateway
• a lease time
• the address of one or more DNS servers (optional)
• the address of one or more WINS servers (optional)
Figure 13-1. DHCP Request Process
Depending on how you configure the ProCurve Secure Router, the router can
act as the DHCP server and/or one of its interfaces can act as a DHCP client.
(However, an interface that acts as a DHCP client cannot also act as a server.)
The ProCurve Secure Router as a DHCP Server
A router that also functions as a DHCP server is particularly useful for a small-
to-medium site at which all subnets connect to the WAN router. The ProCurve
Secure Router can connect to up to two switches on its Ethernet ports.
