DHCP Set Up Overview

Configuring DHCP Address Pools

The DHCP Server is configured by performing the following:

•Allocate one or more address pools for DHCP clients. These pools can specify addresses on the local subnets of the router or external subnets whose clients reach the DHCP Server using BOOTP Relay.

•Exclude any addresses from these pools which must restricted and map to the DHCP pool.

•For each pool, define the set of DHCP network configuration values to be supplied to clients.

•Add manual (static) bindings to the DHCP pool configuration.

•Enable the DHCP Server on a FastEthernet interface only.

Configuring DHCP - Network Configuration Parameters

The DHCP Server can supply network configuration parameters; e.g., the IP address of the DNS Server to its clients.

A DHCP client may require a large set of configuration parameters. Likewise, a network may contain a variety of different client types, each needing a different (possibly unique) set of network parameters.

The XSR’s DHCP setup is minimized for elaborate configuration by the use of scopes.

Configuration Steps

Only four steps are required to minimally configure DHCP Server. They are:

•Create an IP Local Client Pool

•Create a Corresponding DHCP Pool

•Configure DHCP Network Parameters

•Enable the DHCP Server

Optionally, you can also:

•Set up a DHCP Nested Scope

•Configure a DHCP Manual Binding

These steps are described in the following sections.

Create an IP Local Client Pool

Begin DHCP configuration by specifying a pool of IP addresses for clients on a local or remote subnet (set via BOOTP Relay Agent). For this example, the local interface is assigned IP address 1.1.1.2 255.255.255.0.
