Step 1
ip domain name name
Example:
Router(config)# ip domain name smallbiz.com
Router(config)#
Identifies the default domain that the router uses to
complete unqualified hostnames (names without a
dotted-decimal domain name).
Step 2
ip name-server server-address1
[server-address2...server-address6]
Example:
Router(config)# ip name-server 192.168.11.12
Router(config)#
Specifies the address of one or more Domain Name
System (DNS) servers to use for name and address
resolution.
Step 3
ip dhcp excluded-address low-address
[high-address]
Example:
Router(config)# ip dhcp excluded-address
192.168.9.0
Specifies IP addresses that the DHCP server should
not assign to DHCP clients. In this example, we are
excluding the router address.
Step 4
ip dhcp pool name
Example:
Router(config)# ip dhcp pool dpool1
Router(config-dhcp)#
Creates a DHCP address pool on the router and
enters DHCP pool configuration mode. The name
argument can be a string or an integer.
Step 5
network network-number [mask |
prefix-length]
Example:
Router(config-dhcp)# network 10.10.0.0
255.255.255.0
Router(config-dhcp)#
Defines subnet number (IP) address for the DHCP
address pool, optionally including the mask.
Step 6
import all
Example:
Router(config-dhcp)# import all
Router(config-dhcp)#
Imports DHCP option parameters into the DHCP
portion of the router database.
Step 7

Example:
Router(config-dhcp)# default-router
10.10.10.10
Router(config-dhcp)#
Specifies up to eight default routers for a DHCP
client.
