DESIGN

A corporate network is to be designed which has its main office in New York and branches in New Delhi, Bangalore

and Jamshedpur. In various offices according to needs of that branch, particular protocol is used for effective intra

communication. After this for efficient inter communication between main office and branches a cloud server is

used.

Scenario at each office is given according to following

NEW YORK Main office of XYZ organisation is located in New York. Two primary switches are used, both multilayer switches to

enable inter VLAN routing. 6 pcs have been used to denote certain fields. A PAT router has been used to connect the

main branch

COMMANDS______________________________________________________________________ Assign IP addresses to serial and fast Ethernet ports:

Router>enable

Router#config t

Router(config)#int s0/n or fa0/0 // n=0,1…n

Router(config)#IP add IP address subnet mask // range used here is of class C and class A

Router(config)#no shut

Router(config)#IP NAT inside

Router(config)#int s0/0

Router(config)#IP NAT outside

Router(config)#Access-list ACL no permit ethernet n/w address subnet mask //ACL no, range is 1-99, here ACL no->1

Router(config)#IP NAT inside source list int s0/0 overload

NOTE:

IP of PCs is assigned by click on pc->desktop->IP configuration -> subnet mask -> default gateway

NEW DELHI Two switches are required for two floors of a corporate building. Both floors have similar 3 blocks. Requirement is

such that we require to establish connection between only that particular department eg R&D of ground floor can

only establish connection with R&D of 1st floor. Departments here include R&D, Infra & Consulting. Main router in

connected to switch on ground floor. A PAT router is required to translate the inside IPs to exterior Frame relay.

NOTE:


BANGLORE Bangalore being a huge it hub requires a more efficient network topology as the load will be more here. For this

purpose, the concept of VTP will be used. By VTP protocol we will create a server with domain name

programming.org which will be accessed by two clients. VLANs will be defined as default, C, CPP, JAVA & PYTHON.

Client switch will be connected to a PAT router not a main one to reduce chances of congestion.

NOTE:


JAMSHEDPUR

Jamshedpur being a moderate range town with not much clients. City being prone to server failures, to overcome

this HSRP protocol is used where on priority basis two server switches are used namely Mains and Standby. A virtual

IP is assigned which is used as gateway in division 1,2 &3. A PAT router is used which is connected to Main switch

server on one port and on the other to Frame relay.

NOTE:


FRAME RELAY – The Cloud Server REQUIREMENT

1.ROUTER 4 NOS for each destiNATion.

2.Cloud PT

STEPS___________________________________________________________________________ 1.Place the routers and cloud server

2.Assign IP to Head Office and to subsequent branches

3. write the command for Frame relay


Router>enable

Router#config t


Router(config)#IP add IP address subnet mask // range used here is of class A


Code for Frame Relay:


Router(config)#encapsulation frame-relay


SUBINTERFACES (This command will be performed for all the 3 sub offices)

Router(config)#int s0/0.dlci number

Router(config-subinterface)#IP add IP address subnet mask

Router(config-subinterface)#frame-relay inter dlci dlcinumber

Router(config-subinterface)#no shut

In the end all the ports of sub interfaces are connected from the cloud server from one end and with other end it

communicates to its respective office.
