When you start studying for cisco ccna exam the only thing that bothers you is the practice lab.There are several simulators available in market to simulate cisco ccna labs .The simulator which i use is GNS3.The GNS3 allows you to simulate any network for practice labs and the main advantage is that it uses real cisco IOS. You can find out about GNS3 and how to configure it from my previous article Step By Step Using And Configuring GNS3 Cisco Router simulator..The first cisco ccna lab that we are going to perform is static routes .I have access to physical cisco hardware but i will be providing you a GNS3 simulator file also . Lets start up by configuring some static routes on cisco routers and get one more step closes to your ccna certification.
If you have physical hardware you will need .
If you have physical hardware you will need .
- 3 cisco routers . One cisco router with two serial interfaces and Two cisco routers with single serial interface.
- 2 Serial cables, Back to back DTE/DCE cables
- One console cable
The topology that we are going to use is as shown in the figure . You can download the topology as GNS3 file from here. Right click and save target as.
Now Lets start with the configuration
Note:-The router R1 is a DCE device the DCE end of the cisco serial cable should be connected here not the DTE side.It provides clocking to other routers.If the clock is not set the connection will not work.

We will fist configure Router2 (Cisco 2650XM).
(i have a 2650 xm so i type it this way if you have 2500 series you will type just int s0)
enable
configure terminal
hostname Router2
enable secret routemybrain
int s0/0
(i have a 2650 xm so i type it this way if you have 2500 series you will type just int s0)
ip address 192.168.1.2 255.255.255.0
no shutdown
exit
ip route 194.1.1.0 255.255.255.0 192.168.1.1
end
write
Now we will configure Router3.
enable
configure terminal
hostname Router3
int s0/0
ip address 194.1.1.3 255.255.255.0
no shutdown
exit
ip route 192.168.1.0 255.255.255.0 194.1.1.1
end
write
Now we will configure our DCE device Which is Router1
enable
configure terminal
hostname Router1
int s0/0
ip address 192.168.1.1 255.255.255.0
clock rate 64000
no shutdown
int s0/1
ip address 194.1.1.1 255.255.255.0
clock rate 64000
no shutdown
end
write
Now you have a Cisco ccna lab with static routes you can just ping devices with each others Ip address .You can also verify using the command
show cdp neighbors
Thanks to Routemybrain !!!!! Cheers :)
