How to assign an IP address to the switch, router, and PC in the Cisco packet tracer?
Assigning the IP address is the first step while creating a network in packet tracer. Before proceeding with any other configuration, we must assign the appropriate IP address and design the correct IP addressing scheme for the network.
Assigning IP address to switch in packet tracer
As the switch is a layer 2 device, we cannot assign the IP address to the layer 2 device however IP address can be assigned to the virtual interface.
We can assign the IP address to the VLAN1 interface.
The following commands can be used to configure the IP address on the Cisco switch
Switch(config)#interface vlan 1
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#no shut
Configure the IP address on the router in packet tracer
We can assign the IP address on the different types of available interfaces on the router like Ethernet, fast Ethernet, serial, etc.
To assign the IP address, we will enter into the interface configuration mode and then the IP address can be assigned to the router.
The following commands can be used to configure the IP address on the Cisco router
Router(config)#interface gigabitEthernet 0/0
Router(config-if)#ip address 192.168.10.1 255.255.255.0
Router(config-if)#no shutdown
Configure PC IP address in the Cisco packet tracer
To configure the IP address on a PC, laptop, or server, we have to open the IP configuration utility provided in the packet tracer.
To assign the static IP address, we will select the static option available and then we will configure the IP address manually.
Please check the image below showing the manually configured IP address. To assign the IP address through DHCP, we must select the DHCP option however we should have the DHCP server configured to lease the IP address to the devices.
After assigning the IP addresses to different devices, we can check the connectivity with the ping command.
If we have configured the devices with the correct IP addresses then we can further develop our network in the packet tracer.
To assign appropriate IP addresses, we should know how IP subnets work. And how we can create different networks while setting up the network in simulation or the real world?
To learn IPv4 subnetting, you can check subnetting practice questions available for different classes of subnets.
