Configuring Static Route in a real world Scenario

In the last post which was the first part of our tutorial, we discussed static routes, different between static and dynamic routes, basic of static routes, Default routes, then we saw at the syntax of static & default routes and all other stuffs. now that we have understand the basics of static route and how to configure it, here in this post I am going to configure the Static route using a real world scenario example. so stay with us ....... J

Part1: Static Routes in the Cisco IOS

Part2: Configuring Static Routes using a real World Scenario

Note: You can use Packet Tracer 5.3.3 to Practice this tutorial.

The Big Picture

Let’s assume that a Multinational Company has recently opened its branch office in Kabul, Afghanistan and has hired you as their Network Engineer, now they wants you to connect them with their headquarter which is located in the New York, USA. The branch and headquarter are connected by a WAN T1 circuit. Not only that, but they have two more routers in their Kabul branch which have two small Ethernet networks connected in to their LAN sides,  so they wants you to connect them to those networks as well, and they want you to do all these using Static and Default Route. Following is the big picture of our scenario. 

In above Scenario, as you can see that KBL-2 and KBL-3 are our two routers which have a small Ethernet networks connected with them and uses 192.168.1.0/24 and 192.168.2.0/24 networks respectively. Furthermore both KBL-2 and KBL-3 are connected with KBL-1 using 2.1.1.0/30 and 3.1.1.0/30 networks respectively and KBL-1 is connected with NY-HQ which is our New York Headquarter using 1.1.1.0/30 network.  Hopefully I have explained everything well and now it time of configuration. We will start our configuration from KBL-1. 

Configuring KBL-1

KBL-1 is a router which is located in Kabul and is connected with KBL-2, KBL-3 and NY-HQ trough Serial port S 0/0/0, S 0/0/1 and S 0/1/0 using 2.1.1.0/30, 3.1.1.0/30 and 1.1.1.0/30 networks respectively.

First we will get into global configuration mode from privileged mode where we will change the name of this router to KBL-1 by using the hostname command.

Router>
Router>enable
Router#configure t
Router(config)#hostname KBL-1

Now from global configuration mode get into serial interfaces, assign them IP and turn their status to  UP.

KBL-1(config)#interface serial 0/0/0
KBL-1(config-if)#ip address 2.1.1.1 255.255.255.252
KBL-1(config-if)#no shutdown
KBL-1(config-if)#exit
KBL-1(config)#interface serial 0/1/0
KBL-1(config-if)#ip address 1.1.1.1 255.255.255.252
KBL-1(config-if)#no shutdown
KBL-1(config-if)#exit
KBL-1(config)#interface serial 0/0/1
KBL-1(config-if)#ip address 3.1.1.1 255.255.255.252
KBL-1(config-if)#no shutdown
KBL-1(config-if)#exit

Now that interfaces are up, we are ready to configure the static route and by doing this our KBL-1 configuration is finish and our KBL-1 is ready.

KBL-1(config)#ip route 192.168.1.0 255.255.255.0 2.1.1.2
KBL-1(config)#ip route 192.168.2.0 255.255.255.0 3.1.1.2
KBL-1(config)#ip route 0.0.0.0 0.0.0.0 serial 0/1/0
KBL-1(config)#

Configuring KBL-2

Our KBL-2 router is connected with KBL-1 trough Serial interface S 0/0/0 using 2.1.1.0/30 network and has a small Ethernet network connected with it trough interface FastEthernet 0/0 using 192.168.1.0/24 network.  here is the complete configuration for this router.

Router>
Router#configure t
Router(config)#hostname KBL-2
KBL-2(config)#interface serial 0/0/0
KBL-2(config-if)#ip address 2.1.1.2 255.255.255.252
KBL-2(config-if)#no shutdown
KBL-2(config-if)#exit
KBL-2(config)#interface fastEthernet 0/0
KBL-2(config-if)#ip address 192.168.1.1 255.255.255.0
KBL-2(config-if)#no shutdown
KBL-2(config-if)#exit
KBL-2(config)#ip route 0.0.0.0 0.0.0.0 2.1.1.1
KBL-2(config)#

Configuring KBL-3

Our KBL-3 router is connected with KBL-1 trough Serial interface S 0/0/0 using 3.1.1.0/30 network and has a small Ethernet network connected with it trough interface FastEthernet 0/0 using 192.168.2.0/24 network.  here is the complete configuration for this router.

Router>
Router>enable
Router(config)#hostname KBL-3
KBL-3(config)#interface fastEthernet 0/0
KBL-3(config-if)#ip address 192.168.2.1 255.255.255.0
KBL-3(config-if)#no shutdown
KBL-3(config-if)#exit
KBL-3(config)#interface serial 0/0/0
KBL-3(config-if)#ip address 3.1.1.2 255.255.255.252
KBL-3(config-if)#no shutdown
KBL-3(config-if)#exit
KBL-3(config)#ip route 0.0.0.0 0.0.0.0 3.1.1.1
KBL-3(config)#

Configuring NY-HQ

The NY-HQ router is located in our Headquarter New York, USA which is connected to KBL-1 through Serial interface S0/0/1 and has a Ethernet network connected with it through FastEthernet 0/0 using 1.1.1.0/30 and 192.168.5.0/24 network respectively.

Router>
Router>enable
Router#host
Router#configure t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname NY-HQ
NY-HQ(config)#interface serial 0/0/1
NY-HQ(config-if)#no shutdown
%LINK-5-CHANGED: Interface Serial0/0/1, changed state to up
NY-HQ(config)#interface fastEthernet 0/0
NY-HQ(config-if)#ip address 192.168.5.1 255.255.255.0
NY-HQ(config-if)#no shutdown
NY-HQ(config-if)#exit
NY-HQ(config)#
NY-HQ(config)#ip route 0.0.0.0 0.0.0.0 serial 0/0/1
NY-HQ(config)#

Summary

With all these configuration, finally our Static route tutorial comes to an end and now that everything is setup PC-1, PC-3 and PC-5 should communicate between each other and to check their communication you can ping them from each other and ping should give 100% replay. if you have any question regarding this Tutorial feel free to ask and comment i will try my best to give you a response as quick as i can. till then my God be with you.
