How to connect 5 switch with 1 router in Cisco Packet Tracer

Assuming you know the networking basics and how to use Cisco packet tracer.

Configure on your switch interface facing the router as below:

In Switch 1:

#inter fa0/1

#no switchport mode Trunk

#switchport mode access

#switchport access vlan 10

#exit

In Switch 2:

#inter fa0/1

#no switchport mode Trunk

#switchport mode access

#switchport access vlan 20

#exit

Same thing goes for Switch 3,4,5 respectively

Configuration on the Router:

inter giga0/0
no ip address
interface g0/0.1
encapsulation dot1q 10
ip address 192.168.0.1 255.255.255.0

no shutdown

inter giga0/1
no ip address
interface g0/1.1
encapsulation dot1q 20
ip address 192.168.1.1 255.255.255.0

inter giga0/2
no ip address
interface g0/2.1
encapsulation dot1q 30
ip address 192.168.2.1 255.255.255.0
