Configuring Dynamic Host Configuration Protocol

The Dynamic Host Configuration Protocol (DHCP) is used to enable hosts

(DHCP clients) on an IP network to obtain their configurations from a server

(DHCP server). This reduces the work necessary to administer an IP network. The

most significant configuration option the client receives from the server is its IP

address.

Perform the following tasks to configure DHCP. Begin in global configuration

mode.

Configuration Example

In the following example, three DHCP address pools are created: one in network

172.16.0.0, one in subnetwork 172.16.1.0, and one in subnetwork 172.16.2.0.

Attributes from network 172.16.0.0, such as the domain name, DNS server,

NetBIOS name server, and NetBIOS node type, are inherited in subnetworks
