cisco packet tracer scenario and configuration

in this senario ,i will provide three cases

case 1

one of cisco router interfaces will be DHCP client

case 2

cisco router will act as DHCP server provide ip address,subnetmask , default gateway,dns address and tftp address 

case 3

cisco router will act as DHCP rely agent btween DHCP client and DHCP server on different network address

case 1 commands :

Router(config-if)#exit

Router(config)#interface Ethernet1/0

Router(config-if)#ip add dhcp

Router(config-if)#no sh

case 2 commands :

Router(config)#interface Ethernet1/1

Router(config-if)#ip address 13.0.0.1 255.0.0.0

Router(config)#ip dhcp pool net4

Router(dhcp-config)#network 13.0.0.0 255.0.0.0

Router(dhcp-config)#default-router 13.0.0.1

Router(dhcp-config)#dns-server 10.0.0.2

Router(dhcp-config)#option 150 ip 10.0.0.2

Router(dhcp-config)#exit

Router(config)#ip dhcp excluded-address 13.0.0.1 13.0.0.10

Router(config)#ip domain-name 10.0.0.2

case 3 commands:

Router(config)#interface FastEthernet0/0

Router(config-if)#ip address 10.0.0.1 255.0.0.0

Router(config-if)#ip helper-address 10.0.0.2

Router(config-if)#no shutdown

Router(config-if)#exit

Router(config)#interface FastEthernet0/1

Router(config-if)#ip address 11.0.0.1 255.0.0.0

Router(config-if)#ip helper-address 10.0.0.2

Router(config-if)#no shutdown

i made all these cases on one Packet tracer lab , i attached the pkt file with this document.
