Packet Tracer: Rou.ng

Previously, we set up a single router that connects two networks, so no rou7ng policy needs to be configured. In this lab, you will first need to learn from the next sec7on, “Router CLI terminal”, how to set up sta7c/dynamic rou7ng policies.

The following are brief explana7ons of some commonly used commands for seGng up routers: Switching Different Modes

Router>

Router>enable

Router#

Router# configure terminal

Router(config)#

Router(config)# exit

The Show Command

When you set up your network topology, try the following:

Router# show ?

Router# show interfaces

Router# show ip interface brief

Router# show ip interface FastEthernet 0/1

The Interface Command

To review what you have configured, such as IP address for a specific router interface, in “Configure Mode”, specify the “interface-name interface-number(slot/port)”

Router(config)# interface FastEthernet 0/1

Router(config-if)# ip address 192.168.1.5 255.255.255.0

Router(config-if)# no shutdown

Router(config-if)# exit

AVer seGng up its corresponding IP address and subnet mask, don’t forget to make it work by typing “no shutdown”. Then “exit”, to use “show” command for this interface to check if the previous seGng is successful.

Add/Remove sta?c routes

Sta7c routes tell a router where to send packets for a network that this router does not connect to directly.

In this case, the router will forward this packet to an interface of one of the routers that this router directly connects to.

Checking the exis7ng rou7ng table:

Router# show ip route

Router(config)# ip route 192.168.2.0 255.255.255.0 192.168.3.1

If you want to remove this sta7c rou7ng policy, just use “no” format:

Router(config)# no ip route 192.168.2.0 255.255.255.0 192.168.3.1

Add a Dynamic Rou?ng Protocol – OSPF

Router(config)# router ospf 1

Router(config-router)# network 192.168.0.0 0.0.255.255 area 1

Q1. Create a network topology for Bank of China, considering the main components to support the following:

• Bank Location
• The Headquarters in Beijing:
• Executive/Admin Office: Office PCs for management and administrative staff.
• IT Department:
• Customer Service Department: Equipped with staff PCs for handling client services.
• Server Room:
• Web Server
• Customer Database Server
• Transaction Server
• The bank has at least three branches in different towns. For example:
• Branch 1 – Shanghai:
• Accounts Department
• Loan Services Department
• Branch 2 – Guangzhou:
• Customer Service Department
• Branch 3 – Shenzhen:
• IT Department
• Each department/office is expected to be on its own separate IP network.
• The switches should be configured with appropriate LANs using VLANs.
• OSPF should be used to provide routing for routers in the internal network. Static routing should be used for the external cloud-based email server.
• Devices in the IT Department of the Shanghai Branch should acquire dynamic IP addresses via a router based DHCP server.
• The IP address for all subnets should begin with your UCD student number as the bank’s identifier number. For example, if the number is 192 022 02, then it should be 192.22.2.x. Use at least (could be longer) 25 bits as your network prefix.
• You can estimate the number of IP addresses in any subnet, but it should be reasonable based on the expected devices.

Q6. Demonstrate your understanding of how broadcast messages function within a department, at headquarters, and throughout the entire bank based on your network design.

Submission:

• .pkt file for the network topology (Logical and Physical)
• A PDF report with answers for the “Questions,” supporting all your answers with screenshots
• A short video (Max: 3 minutes) to explain and test your network topology
