Static Routing

Static Routing Between Two Routers Using Cisco Packet Tracer

By: Douglas Fessler

Objective

This lab demonstrates configuring static routing between two routers using Cisco Packet Tracer. The goal is to establish connectivity between devices in different subnets by manually adding static routes. This is a foundational skill for small networks where dynamic routing protocols are not necessary.

Tools Used

• Software: Cisco Packet Tracer

• Devices:

  • Two Cisco 2811 routers

  • Two PCs (one connected to each router)

• Connections: Crossover Ethernet cables

• Configurations: Static routing

Network Topology

·  Router 1 (R1):

• Interface GigabitEthernet0/1: IP 192.168.1.1/24

• Interface GigabitEthernet0/0: IP 10.0.0.1/30

• Connected PC: IP 192.168.1.2/24

·  Router 2 (R2):

• Interface GigabitEthernet0/1: IP 192.168.2.1/24

• Interface GigabitEthernet0/0: IP 10..0.0.2/30

• Connected PC: IP 192.168.2.2/24

Configuration Steps

Here’s how I configured the routers step-by-step:

Assign IP Addresses to Router Interfaces

o    On Router 1:

R1> enable 

R1# configure terminal 

R1(config)# interface FastEthernet0/0 

R1(config-if)# ip address 192.168.1.1 255.255.255.0 

R1(config-if)# no shutdown 

R1(config-if)# interface FastEthernet0/1 

R1(config-if)# ip address 10.0.0.1 255.255.255.252 

R1(config-if)# no shutdown 

o      On Router 2:

R2> enable 

R2# configure terminal 

R2(config)# interface FastEthernet0/0 

R2(config-if)# ip address 192.168.2.1 255.255.255.0

 R2(config-if)# no shutdown

 R2(config-if)# interface FastEthernet0/1 

 R2(config-if)# ip address 10.0.0.2 255.255.255.252

 R2(config-if)# no shutdown 

R2(config-if)# no shutdown

Configure Static Routes

·         On Router 1:

R1(config)# ip route 192.168.2.0 255.255.255.0 10.0.0.2 

·         On Router 2:

R2(config)# ip route 192.168.1.0 255.255.255.0 10.0.0.1

Verify Connectivity

• Use the ping command to test connectivity between the PCs.

Results

After completing the configurations, I verified the connectivity by pinging from PC1 (192.168.1.2) to PC2 (192.168.2.2). The pings were successful, indicating the static routes were configured correctly.

Challenges and Solutions

During the lab, I encountered a minor issue where the router interfaces were initially down. I resolved this by ensuring the no shutdown command was applied to all interfaces.

Real-World Applications

Static routing is commonly used in small networks where simplicity is preferred over dynamic routing protocols. This lab demonstrates the ability to configure and troubleshoot static routes—a critical skill for network administrators managing small office or branch networks.

Reflection

This exercise reinforced my understanding of IP addressing and static routing. It also improved my troubleshooting skills, particularly in ensuring interfaces are active and configured correctly before verifying connectivity.
