NETWORK CONFIGURATION AND TESTING2
Introduction
The task includes use of ospf and eigrp routing protocols. The report begins by
describing the protocols, lists the benefits, mentions the best practices and discusses the
configuration. Next testing is conducted through test cases with screenshots. After this the
report ends with conclusions.
Design Section Task I
1. What is OSPF in your own words and reference
OSPF stands for Open Shortest Path First and is a routing protocol for Internet Protocol
(IP) networks. This routing method makes use of LSR or Link State Routing algorithm that
corresponds to the Interior Gateway Protocol (IGP) and operates through a single
autonomous system (AS). The OSPF routing method supports Classless Inter-Domain
Routing (CIDR) model of IP addressing.
2. What is EIGRP in your word and reference
Benefits of using OSPF
OSPF is a true route-free loop routing protocol which is made possible thanks to the
efficiency of the algorithm used.
OSPF Fast Convergence: It is made possible to transmit the changes to the overall automated
system in shortest possible time.
In this routing the autonomous system gets divided to multiple regions, the routing
information summary can be adopted and that results in reduction of the amount of network
transmission
The routing uses multicast addresses instead of a broadcast address in the broadcast networks
to reduce interference of other network devices.

NETWORK CONFIGURATION AND TESTING3
Different network types can be accessed in multiple times through broadcast and NBMA by
election of DR and number of route exchanges.
OSPF offers interface-based plaintext and MD5 authentication.
Benefits of using EIGRP
Convergence of EIGRP is observed at fast and rapid response times for network topology
changes.
EIGRP makes more effective use of links through Equal Cost Multi Path or ECMP and
unequal cost load sharing techniques.
Easier transition is performed by means of multi-address family.
Both IPv4 and IPv6 network connections are supported by the routing method.
Network traffic gets reduced by EIGRP via use of need based updates
Show why is these protocols are chosen and are feasible to use
Both the routing methods EIGRP and OSPF are interior routing protocols that help
organizations like International Banking Corp (IBC) to appropriately configure the different
segments of their network. Additionally the routing protocols help in choosing best routes for
data transfer between routers and offers better performance than say RIP routing.
Best practice for OSPF
The best practices for configuring OSPF routing involves the following:
Setting Router IDs
Accurate defining of networks
Default configuration of passive interfaces
Use of different OSPF authentication for every neighbour

NETWORK CONFIGURATION AND TESTING4
Ensuring redistribution of route maps and static routes
Best practice for EIGRP
Use of different AS number than what is being used on IGP
Use of stub routing concept offered by EIGRP
Configuring appropriate IP addressing scheme and summarizing of networks
Use of on-demand libraries provided by vendors like Cisco
Task 2 Implementation
Basic Configuration
The configuration of routers of IBC involves specifying the IP addresses on all the
respective interfaces being used. Then the networks used by these interfaces need to be added
to the routing protocol being applied EIGRP or OSPF. The serial interface IP addresses of
two routers must be specified interchangeably as the remote interface for BGP configuration
on a specific router.
The IP addresses must be specified in order to uniquely identify the router interface in
the network. After that the networks in use need to be added to the routing protocol to ensure
connectivity throughout the network segment. BGP neighbour interfaces need to be
configured to ensure working of the Border Gateway Protocol.
These configurations are applied by entering specific commands in the CLI terminal of the
router. Some of the commands are as follows:
#R8
int s0/2/0

NETWORK CONFIGURATION AND TESTING5
ip address 10.10.48.2 255.255.255.0
router eigrp 150
network 10.10.48.0 255.255.255.0
#R4
int s0/2/0
ip address 10.10.48.1 255.255.255.0
router eigrp 150
network 10.10.48.0 area 0
Initial configuration of IBC with the interface links of routers marked red representing they
are down.
Interface links of routers after configuration are green, representing they are up.

NETWORK CONFIGURATION AND TESTING6
Hostnames of routers are changed as per name of the router.

NETWORK CONFIGURATION AND TESTING7
IP addresses on specific interfaces as shown in IBC network diagram provided are configured
appropriately.
Tasks 2 Enable OSPF on Relevant Routers
To configure OSPF on relevant routers the ospf routing number needs to be specified
followed by adding of the respective networks to the ospf routing while also specifying the
area.
This is performed to create internal network configuration for specific segments of the
IBC network. This will prevent network traffic overhead on a particular routing technique if
commonly applied for all network segments and ensure network security.
The ospf routing can be applied by entering specific commands in the terminal window like
