Configuring A Router Interface As A Dhcp Client; Client Receiving The Wrong Fixed Dhcp Address - HP ProCurve Secure 7000dl Series Basic Management And Configuration Manual

Dynamic Host Configuration Protocol (DHCP)

Configuring a Router Interface as a DHCP Client

A router interface must have its primary address on the subnet specified in
the pool in order to respond to requests. You should also check that the DHCP
network matches the address for the connecting router interface.

Client Receiving the Wrong Fixed DHCP Address

If a host is unable to get the fixed address you configured for it in a single host
DHCP pool, or if it receives an address from a different pool, check the
running-config. Make sure that you have not excluded the fixed address.
Configuring a Router Interface as a
DHCP Client
Your service provider may require the router to receive an address from one
of its DHCP servers. For example, some Frame Relay providers conserve IP
addresses by only assigning them to a PVC endpoint when the PVC is open
and active. In this case, you must configure the WAN interface that connects
to the provider as a DHCP client.
Ethernet interfaces can also be DHCP clients. For example, the interface could
take an address from a server on the local network. When possible, it is a good
idea to assign network devices static addresses. However, DHCP does auto-
matically track IP addresses assigned to devices as well as which addresses
are still available, relieving IT staff of this task. You can configure the DHCP
server to assign the Ethernet interface a fixed DHCP address.
Interfaces that receive a DHCP address can receive other configurations, too.
This is particularly useful for interfaces that connect to the Internet. For
example, an ATM subinterface can receive the address for a DNS server.
To learn about assigning various types of IP addresses to interfaces, see

Data Link Layer Protocol for E1, T1, and Serial Interfaces, Chapter 7: ADSL
WAN Connections, and Chapter 8: Configuring Demand Routing for Pri-
mary ISDN Modules.
