CASE STUDY 1 ANALYZING THE PERFORMANCE OF VARIOUS CONFIGURATIONS AND PROTOCOLS IN

1.1. Establishing a Local Area Network (LAN)

The main objective is to set up a Local Area Network,concepts involved in this network are IP addressing and the Address Resolution Protocol (ARP). The required equipment's are 192.168.1.1 ,192.168.1.2, 192.168.1.3,Host A Host B Host C, Switch/HUB, three PC`s equipped with at least one NIC, one HUB or Switch and the necessary cables. Once the physical LAN is set up the hosts need to be configured using the ifconfig command. To verify communication among the machines the ping command is used. Next, to manipulate the routing tables at the hosts to understand how machines know where to send packets. Since the ifconfig command places a default route into the routing tables this route must be deleted. to blindfold the machine. The ping command is used again to show that communication is no longer available. To re-establish communication the routes are put back into the routing table one host at a time. Communication i once again verified using the ping command.

REQUIREMENTS:

3 Windows PC or 3 Linux PC, Each PC must Have One NIC cards.
1 Switch (8 port) or 1 Hub.

1.2. Connecting two LANs using multi-router topology with static routes :

The main objective is to extend routing connection by using multiple routers. The concepts include IP addressing and basic network routing principles. Connect two LANs topology. During router configuration attention is paid to the types of interfaces as additional issues are involved with set-up. For example, the serial interfaces require clocking mechanisms to be set correctly. Once the interfaces are working the ping command is used to check for communication between LANs. The failure of communication illustrates the need for routes to be established inside the routing infrastructure. Static routes are used to show how packets can be transported through any reasonable route. It is run trace route on two different configurations to demonstrate the implementation of different routes.

1.3 Analyzing the performance of various configurations and protocols

Original TCP versus the above modified one: To compare the performance between the operation of TCP with congestion control and the operation of TCP as implemented . The main objective is for students to examine how TCP responds to a congested network. The concepts involved in the lab include network congestion and the host responsibilities for communicating over a network. This lab requires three PC’s connected to a switch.One PC is designated as the target host and the other two PC’s will transfer a file from the target host using FTP. A load is placed on the network to simulate congestion and the file is transferred, first by the host using the normal TCP and then by the host using the modified version. This procedure is performed multiple times to determine average statistics. The students are then asked to summarize the results and draw conclusions about the performance differences and the underlying implications for hosts operating in a network environment.

CASE STUDY 7 CONFIGURING A FIRE WALL

Consider a Fire wall communication server with single inbound modem. Configure the modem to ensure security for LAN

What is Firewall?

A firewall is a layer of security between your home network and the Internet. Since a router or modem is the main connection from a home network to the Internet, a firewall is often packaged with those devices. Every home network should have a firewall to protect its privacy. firewalls are a combination of hardware and software The hardware part gives firewalls excellent performance, while the software part allows firewalls to be tailored to your specific needs.

Firewall Rules :

Firewall rules block or allow specific traffic passing through from one side of the router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to. A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of the modem router are:

Inbound
Outbound

INBOUND RULES :

Block all access from outside except responses to requests from the LAN side

OUTBOUND RULES :

Allow all access from the LAN side to the outside.

NOTE :

You can define additional rules that will specify exceptions to the default rules. By adding custom rules, you can block or allow access based on the service or application, source or destination IP addresses, and time of day. You can also choose to log traffic that matches or does not match the rule you have defined.

CASE STUDY 2 RIP AND OSPF Redistribution

This case study addresses the issue of integrating Routing Information Protocol (RIP) networks with Open Shortest Path First (OSPF) networks. Most OSPF networks also use RIP to communicate with hosts or to communicate with portions of the inter-network that do not use OSPF. This case study should provide examples of how to complete the following phases in redistributing information between RIP and OSPF networks, including the following topics:

Configuring a RIP Network

Adding OSPF to the Center of a RIP Network

Adding OSPF Areas

Setting Up Mutual Redistribution

PHYSICAL CONNECTIONS :

RIP AND OSPF Redistribution

Most OSPF networks also use RIP to communicate with hosts or to communicate with portions of the inter-network that do not use OSPF. Cisco supports both the RIP and OSPF protocols and provides a way to exchange routing information between RIP and OSPF networks.

CISCO 1841 Model 4 Routers.
Two 8 port switchs.
Two End Device PC's

Adding OSPF to the Center of a RIP Network :

A common first step in converting a RIP network to OSPF is to add backbone routers that run both RIP and OSPF, while the remaining network devices run RIP. These backbone routers are OSPF autonomous system boundary routers. Each autonomous system boundary router controls the flow of routing information between OSPF and RIP

ROUTING TABLE :

For a Cisco router, the IOS command show ip route displays the routes in the routing table. There are several types of routes that can appear in the routing table:

Directly-Connected Routes:

When the router powers up, the configured interfaces are enabled. As they become operational, the router stores the directly attached local network addresses as connected routes in the routing table. For Cisco routers, these routes are identified in the routing table with the prefix C. These routes are automatically updated whenever the interface is reconfigured or shutdown.

Static Routes:

A network administrator can manually configure a static route to a specific network. A static route does not change until the administrator manually reconfigures it. These routes are identified in the routing table with the prefix S.

Dynamically-Updated Routes (Dynamic Routes) :

Dynamic routes are automatically created and maintained by routing protocols. Routing protocols are implemented in programs that run on routers and that exchange routing information with other routers in the network. Dynamically-updated routes are identified in the routing table with the prefix that corresponds to the type of routing protocol that created the route, for example R is used for the Routing Information Protocol (RIP).

Default Route :

The default route is a type of static route which specifies a gateway to use when the routing table does not contain a path to use to reach the destination network. It is common for default routes to point to the next router in the path to the Internet Service Provider. If a subnet has only one router, then that router is automatically the default gateway, because all network traffic to and from that local network has no option but to travel through that router.

RIP:

It is a distance vector routing protocol.
send the complete routing table out to all interface every 30 seconds.
Rip only use hop count to determine best way to remote Network.
Maximum allowable hop count is 15

OSPF:

Open Shortest Path First (OSPF) is a non-proprietary link-state routing protocol described in RFC 2328.
identified in the routing table with the prefix O .

Uses the SPF algorithm to calculate the lowest cost to a destination
Sends routing updates only when the topology changes; does not send periodic updates of the entire routing table.
Provides fast convergence
Supports VLSM and discontiguous subnets
Provides route authentication
