1 We have 3 team on A network.
2 Here we will enable 3 VLAN to separate team on a network.
3 by default Vlan 10 will not communicate  with Vlan 20 and 30.
4 same 20 and 30 will not communicate each other.

 Here we can see all switch ports in vlan 1. Now create Vlan as according given team in pic.

Switch#
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Switch(config)#vlan 10
Switch(config-vlan)#name sales
Switch(config-vlan)#exit

Switch(config)#interface range fastEthernet 0/1 -24
Switch(config-if-range)#switchport access vlan 10
Switch(config-if-range)#exit

this was sales team configuration all switch same configuration use.

Management team

Switch#
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Switch(config)#vlan 10
Switch(config-vlan)#name sales
Switch(config-vlan)#exit
Switch(config)#
Switch(config)#interface range fastEthernet 0/1 -24
Switch(config-if-range)#
Switch(config-if-range)#switchport access vlan 10
Switch(config-if-range)#exit

InterVlan Configuration 

way use intervlan routing ?

intervlan routing are use to communicate multiple Vlan.
For example. Vlan 10 want to conect with Vlan 20 we have to do Intervlan routing 

let's look.
 1 . Here we have to different Network in single switch
 2 . Here we have to different Vlan 10 and 20.
 3 . let's see how to get communicate both vlan (intervlan Routing)

Step 1 . First Assign ip address on all pc as given pic.

first network pc..
 
second network pc.
 

Now configure Switch Create Vlan .

Port No 2,3,4 in Vlan 10  & 5,6,7 in Vlan 20 remind it

let's look Sales Team Vlan 10.

Switch#
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Switch(config)#vlan 10
Switch(config-vlan)#
Switch(config-vlan)#name sales
Switch(config-vlan)#exit

Switch(config)#interface range fastEthernet 0/2 -4
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#switchport access vlan 10
Switch(config-if-range)#exit
Switch(config)#

IT Team Vlan 20 

Switch(config)#vlan 20
Switch(config-vlan)#name IT
Switch(config-vlan)#exit
Switch(config)#
Switch(config)#interface range fastEthernet 0/5 - 7
Switch(config-if-range)#
Switch(config-if-range)#switchport mode access
Switch(config-if-range)#
Switch(config-if-range)#switchport access vlan 20
Switch(config-if-range)#exit
Switch(config)#

 We have to make Trunk port witch is connected to Router.

Switch#
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#
Switch(config-if)#switchport mode trunk
Switch(config-if)#

Without create it trun we can not transfer vlan to vlan packet .

now ping (Vlan 10 ) pc 1 to ( Vlan 20 ) pc 1
