Answer / jitendera kumar sinha
onfigure an IP address on the router's Ethernet por
Router(config-if)#ip address 1.1.1.1 255.0.0.0
Router(config-if)# no shutdown
Create a DHCP IP address pool for the IP addresses you want to use.
Router(config)# ip dhcp pool mypool
Specify the network and subnet for the addresses you want to use from the pool.
Router(dhcp-config)# network 1.1.1.0 /8
Specify the DNS domain name for the clients.
Router(dhcp-config)#domain-name mydomain.com
Specify the primary and secondary DNS servers.
Router(dhcp-config)#dns-server 1.1.1.10 1.1.1.11
Specify the default router (i.e., default gateway).
Router(dhcp-config)#default-router 1.1.1.1
Specify the lease duration for the addresses you're using from the pool.
Router(dhcp-config)#lease 7
Exit Pool Configuration Mode.
Router(dhcp-config)#exit
This takes you back to the global configuration prompt. Next, exclude any addresses in the pool range that you don't want to hand out.
For example, let's say that you've decided that all IP addresses up to .100 will be for static IP devices such as servers and printers. All IP addresses above .100 will be available in the pool for DHCP clients.
Here's an example of how to exclude IP addresses .100 and below:
Router(config)#ip dhcp excluded-address 1.1.1.0 1.1.1.100
