Introduction to Static Routing

Static routing is a technique used to configure routes in a router manually. It is used to provide a specific path for packets to follow when the destination network is not present in the routing table.

Theory

Static routing uses the following key concepts:

• Static routes: Static routes are used to configure routes in a router manually.
• Route tables: Route tables are used to store the configured routes in a router.

Summary

Static routing is a simple technique used to provide a specific path for packets to follow when the destination network is not present in the routing table. It is commonly used in small networks where the network topology is simple.

Configuration and Verification

R1

R1 Configuration

Router>enable
Router#configure terminal
Router(config)#hostname R1
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.1.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface fastEthernet 0/1
R1(config-if)#ip address 192.168.2.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface serial 0/0/0
R1(config-if)#ip address 192.168.10.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#clock rate 64000
R1(config-if)#exit

Configure Static Routing in R1

R1(config)#ip route 192.168.3.0 255.255.255.0 192.168.10.2
R1(config)#ip route 192.168.4.0 255.255.255.0 192.168.10.2
R1(config)#exit

R1 Verification

R1#show running-config
R1#show ip route
R1#write

R2

R2 Configuration

Router>enable
Router#configure terminal
Router(config)#hostname R2
R2(config)#interface fastEthernet 0/0
R2(config-if)#ip address 192.168.3.1 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#interface fastEthernet 0/1
R2(config-if)#ip address 192.168.4.1 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#interface serial 0/0/0
R2(config-if)#ip address 192.168.10.2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit

Configure Static Routing in R2

R2(config)#ip route 192.168.1.0 255.255.255.0 192.168.10.1
R2(config)#ip route 192.168.2.0 255.255.255.0 192.168.10.1
R2(config)#exit

R2 Verification

R2#show running-config
R2#show ip route
R2#write
