Cisco Networking Lab 2 - Assign the IP Address on Router, Switch and Host Device

In this lab, we are going to assign the IP Address on-device interface. As you can see, this is a basic network topology, hence explaining only the basic Cisco IOS command. Also, we will test the direct connectivity with ping utility.

Task:-

Check the current interface status

Assign IP on the Router and PC

Verify the IP Address

Verify the connectivity from Router to PC and PC to Router

Here I am using GNS3 VE to demonstrate this lab. I have already placed two routers, one switch, one client device. Let us look at the configurations.

Devices to Configure

Routers - R1 (leave the ISP this time)

Ethernet Switch - SW1

Host Device - PC1

R1- Router Configuration

Check the current interface status using the sh ip interface brief command

IP Configuration on Serial Interface

R1#config t

R1#(config)#interface s2/0

R1#(config-if)#no ip address

R1#(config-if)#ip address 10.1.1.2 255.0.0.0

R1#(config-if)#no shutdown

IP Configuration on Ethernet Interface

R1#config t

R1#(config)#interface e0/0

R1#(config-if)#no ip address

R1#(config-if)#ip address 192.168.100.1 255.255.255.0

R1#(config-if)#no shutdown

Verify the IP Address using the sh ip interface brief command

Switch Configuration

Here we are using an Ethernet Switch so there is no need to configure the Switch in this topology. We will discuss other details in later articles.

PC1 - Host Configuration

Check the current IP Address status using the show ip command

IP Configuration

PC>ip 192.168.100.10 /24 192.168.100.1

 Verify the IP Address using the show ip command

Checking the connectivity

We can use ping utility to check the connectivity between the devices. Below are the results.

PC to Gateway

Router to Host

Topic Conclusion

We have configured a basic cisco based network topology and covered almost general commands. In the coming post will configure remote connectivity and static routes.
