ALL in One
This example has included various concepts of networking such as: IP Addressing, DNS
Server, DHCP Server, Wireless and routing through different subnets.

Configuring Routers
Routing (RIP Protocol)

192.168.3.1
192.168.1.1

192.168.2.1

192.168.2.2

Configuring Router 0
Router 0 located between subnet 1 and subnet 2
At the beginning it asks for wizard configuration, we deny by entering no
--- System Configuration Dialog --Continue with configuration dialog? [yes/no]: no

Then Configure the IP address on both interfaces of router R0
For this purpose you must go to configuration mode.
Router>enable
Router#configure terminal

Assign 192.168.1.1/24 to interface in Subnet 1 area and 192.168.2.1/24 to interface in
Subnet 2.

Router(config)#interface fastEthernet 0/0
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#exit

Router(config)#interface fastEthernet 0/1
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#exit

Next step is making connection between different subnets on different interfaces of the
router by configuring the routing protocol in router
Configure RIP version 2 routing protocols then introduce both networks on both interfaces
of router to routing protocol.
Router#configure terminal
Router(config)#router rip
Router(config-router)#version 2
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0
Router(config-router)#exit
Router(config)#exit

Finally save all configuration in Memory of router.
(You should be in Enable Mode)
Router#write memory

Second Router
Doing the same steps to configure the second router.
Router 1 located between subnet 2 and subnet 3

--- System Configuration Dialog --Continue with configuration dialog? [yes/no]: n
Router>enable
Router#configure terminal

Router(config)# interface fastEthernet 0/0
Router(config-if)#ip address 192.168.3.1 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#exit

Router(config)#interface fastEthernet 0/1
Router(config-if)#ip address 192.168.2.2 255.255.255.0
Router(config-if)#no shutdown
Router(config-if)#exit

Router(config)#router rip
Router(config-router)#version 2
Router(config-router)#network 192.168.2.0
Router(config-router)#network 192.168.3.0
Router(config-router)#exit

Router(config)#exit

Router#write memory

Configuring DNS Server
192.168.1.2/24

192.168.1.1/24

Step 1 –

First of all in “Desktop” tab we must assign IP Address, Subnet Mask, Default Gateway and
DNS Server in “IP Configuration”.

IP Address: IP Address of this machine in the network.
Subnet Mask: Subnet mask of assigned IP address to this machine.
Default Gateway: IP Address of the default forwarder gate to outside of the subnet (For
example here we enter the address of fastEthernet 0/0 port of Router0).
DNS Server: IP Address of DNS Server (for DNS Server we assign the IP Address of interface).
