in different way we can configure dhcp
First you need to create a DHCP Pool by the "ip dhcp pool" command
Then you enable the DHCP Service by the "service dhcp"
its easy man
for next time you can ask MR.google
to offer range of ips:
Router(config)# ip dhcp excluded-address172.16.1.100172.16.1.103
- to configer auto DHCP :
Router(config)# ip dhcp pool1
Router(dhcp-config)# network172.16.0.0 /16 ---------->16 mean "lenght"
Router(dhcp-config)# dns server172.16.1.103172.16.2.103 -------> DNS configer
