If there is Network 10.0.0.0 and there is router or 3layer switch How can i Active DHCP protocol by this router write the command?

ROUTER:

conf t

ip dhcp pool xnetwork

network10.0.0.0  255.0.0.0

default-router10.0.0.1

dns-server2.2.2.2 (for example)

exit

! if you want to exclude some ip addresses for dhcp not to leases this ip addresses type this...

ip dhcp excluded-address10.0.0.1   10.0.0.9 (for example)

! now configure the server who ask for an ip address from the router

conf t

interface fa0/0 (for example)

ip address dhcp

no shut

exit

! then in L3SW, configure a DHCP Helper. means,  inform the router /  l3sw that if it receives a dhcp broadcast request, do not drop the packet, instead, forward te broadcast to a preconfigured ip address of a DHCP SERVER.

! for example from l3sw perspective, ip address of the DHCP SERVER is10.0.0.2

L3SW:

conf t

interface vlan1 (for example)

ip  helper-address10.0.0.2

exit

Router

conf t

ip dhcp pool XYZ

network10.0.0.0255.0.0.0

default-network10.0.0.1

end

Layer3 Switch

conf t

interface vlan XYZ

ip dhcp pool XYZ

                     config)# ip dhcp pool xyz)

config)# network10.0.0.0  255.0.0.0)

 config)#  default- router10.0.0.1
