Configuring the DHCP Server with a Configuration Editor

A typical DHCP server configuration provides the following configuration settings for a particular subnet on a Services Router interface:

■An IP address pool, with one address excluded from the pool.

■Default and maximum lease times.

■Domain search suffixes. These suffixes specify the domain search list used by a client when resolving hostnames with DNS. See RFC 3397, Dynamic Host Configuration Protocol (DHCP) Domain Search Option, for more information.

■A DNS name server.

■A DHCP option—Router solicitation address option (option 32). The IP address excluded from the IP address pool is reserved for this option.

In addition, the DHCP server might assign a static address to at least one client on the subnet. Table 38 on page 72 provides the settings and values for the sample DHCP server configuration used in this section.
