hi akram
i know what you need , so follow below
you have default vlan that is vlan 1 : ip address : 192.168.100.1 ...254
you need to create 4 vlan
vlan 2 : 192.168.2.0 ....254
vlan 3 : 192.168.3.0 ... 254
vlan 4 : 192.168.4.0 ....254
you can change the IPs its gor example
first in the router :
go to interface (that connected to your LAN) for example F0/0
do the configuration :
inter f0/0.1
encp dot1q 1
ip address 192.168.100.1 255.255.255.0
ip helper-address ( DHCP Server IP )
no shut
inter f0/0.2
encap dot1q 2
ip address 192.168.2.1 255.255.255.0
ip helper-address ( DHCP Server IP )
no shut
inter f0/0.3
encp dot1q 3
ip address 192.168.3.1 255.255.255.0
ip helper-address ( DHCP Server IP )
no shut
inter f0/0.4
encp dot1q 4
ip address 192.168.4.1 255.255.255.0
ip helper-address ( DHCP Server IP )
no shut
now the router will do routing between VALNs
all users must have default gateway same the router interface ,, user in VLAN 2 Default gateway 192.168.2.1 .......like this for all
,,,,,,,,,,,,
in switches :
all links between switches configure it as trunk port with encap dot1q
and the link between Router and Switch
,,,,,,,,,,,,
in DHCP :
create scoop for each vlan and make sure about default gateway
and make sure the default gateway for DHCP router as the same in router interface
if DHCP in VLAN 1 the default Gateway Must 192.168.100.1
any question please ask

Which switch model are you using for intervlan routing ?

catalyst 2960 series

sorry,I'll use for inter-vla
n router 2600 series for the, vlan catalyst 2960 series

2960 switches generally do not support routing. You might need a layer 3 device. Here is a good document on intervlan routing for Layer 2 switches.
http://www.cisco.com/en/US/tech/tk389/tk815/technologies_configuration_example09186a00800949fd.shtml
You need to configure the Layer 3 device IP address as the default gateway for all the hosts. That will ensure that all traffic is getting routed appropriately.
Hope this helps.

sorry, my problem is how to assign the ip address in my 2600 router for each vlan ,The Windows DHCP server give 192.168.100.1-192.168.100.254
so i will create about 4 vlans what Ip address i will give each vlani n a 2600 router

Hello,
You need to give an IP address in the range of 192.168.100.1 -
192.168.100.254. For simplicity, you can assign 192.168.100.1 as the address
as long as that is available. If not, you can assign any other address. I am
assuming for other VLANs you have a separate IP range. You need to follow
the same logic for other VLANs as well. Once you assign the addresses, you
need to go back to your DHCP server and make 192.168.100.1 as reserved
address so it will not be assigned to anybody else. Also, you need to
configure the DHCP server such that the default router option in the DHCP
reply has 192.168.100.1 as the value. This will ensure that every host in
the network that gets DHCP address sees 192.168.100.1 as the default
gateway. You need to repeat the same exercise for other VLANs as well.
Hope this helps.

I think it's true

The port where is Windows DHCP Server must be configured as Trunk Port in the switch?
