Static Routing and Default Routing Configurations

Network Address of above  pvt network is .  now we have to assign IP address for each and every network .First  we  have to identify  “How many networks are there ?? “  . As you can see on the above picture there are 5 networks. After identify the  networks,  now you can   find subnet marks and IP address for each and every  network devices.

Given network address is in class C . so the subnet address should be . There are 5 networks , so   5<2^3 . so s bytes are available for host.|00000 |                       Subnet 0|00000 |                     Subnet 1|00000 |                     Subnet 2|00000 |                     Subnet 3|00000 |                   Subnet 4|00000 |                   Subnet 5|00000 |                   Subnet 6|00000 |                   Subnet 7  

now assign IP address for each and every devices !!

  Now configure PC-1 first.To configure pc double click on pc and select desktop

IP address 
Subnet mask
Default Gateway

Now double click on 1841 Router 1 and select CLI 
--- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]: no

Press RETURN to get started!
Router#config t
Router(config)#hostname R1
R1(config)#interface fastethernet 0/0
R1(config-if)#ip address
R1(config-if)#no shutdown
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
Now configure serial port on  router with ip address  
R1(config)#interface serial 0/0/0
R1(config-if)#ip address
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
Configure Router-2 and Router-3 in same way .
After configure all device you have to ping and checked whether all packets are delivered correctly. 
Command syntax for static route:
ip route  -  The command used to create the static route.
destination_network  - The network you're placing in the routing table.
mask - The subnet mask being used on the network.
next-hop_address-  The address of the next-hop router that will receive the packet and forward it to the remote network.

ip route [destination_network] [mask] [next-hop_address or exit_interface]
Now tell R1 about to network of ( To R2)

R2(config)#ip route

Now test the connectivity. Go on pc1 and 

C:\> ping

DCCN II  Worksheet 03 

Static Routing Configuration

First you have to downlord the worksheet 03 from moodle  and draw the bellow network and add IP address to each and every PCs and Routers . 

When you are using the cisco packet tracer you can add different type of routers , PCs, Wires etc .
for Design above network you must select two 1841 ciso routers ,  two PCs , Serial DTE and Copper cross over. 
Picture 1.1
When you select 1841router you have to add WIC-1T port because to connect serial.
