How to Experimenting VPN on GNS3 for Networking

A Bank Headquarters are opening two new branches to help serving over populated costumes in the same city.  The two new branches need to connect them to the Headquarter main database servers and data centers.

Each branch will need to have a direct WAN connection to the headquarters. Furthermore, there will be a WAN connection between both branches.  Each branch consist of 3 floors:

  1. The ground floor has 53 connectivity nodes (faceplate) that serve:
  2. 10 customers windows and 3 ATM machines
  3. The finance department 20 connectivity nodes (faceplate)
  4. 20 unused connectivity nodes (faceplate) for expansions in the first floor
  5. First Floor: house the Data center and the Database Center and 80 cable node also each department will have there own IT department.
  6. Second Floor: 80 connectivity nodes (faceplate) and its divided as follow:
  7. 20 connectivity nodes (faceplate) for the Human resources department
  8. 20 connectivity nodes (faceplate) for Management.

Each branch needs to access the Bank headquarters Data to Synchronize the Data, this happens every night after working hours. Each branch router is directly linked to headquarters routers with the following IP address:

Branch A: 10.0.1.0/24
Branch B: 10.0.2.0/24
You and your team are hired to build the Bank Network system and you are required to do the following:
.    Draw a schematics of each branches showing the following:

  1. Each floor connectivity nodes
  2. Equipment room for the backbone of each branch

  1. You need to show the router setting and connectivity assumes IP addresses are static between routers and switches.

  1. Show traffic simulation between floors in each branch

4.  You need to build the network topology using GNS3 showing the topology for each branch and the connectivity between the branches and headquarters.

  1. Using GNS3 show the required bandwidth and traffic in linking between the HQ and the two branches and calculate to total all bandwidth

N x T = BN
Numbers of users (x) Traffic estimate based on usage weight = Bandwidth Needed
Some decent examples on the page above provide insight as to what they consider “light” and “medium” and “heavy” users.
Let’s suppose the following user weight groups are appropriate:
Light user: 4Mbps
Medium user: 20Mbps
Heavy user: 50Mbps
The policy are set as follows nothing we’ve simply one Mbps overall information measure over simulated GNS3 interfaces. FTP are given Priority information measure of 256 Kbps. Web Traffic are given 512 Kbps.
File sharing traffic are policed at 128 Kbps and therefore the exceeded traffic won’t be born. Instead it’ll be remarked with DSCP price CS1 and that we will use the new marking anon. Also, a secure information measure of 128 Kbps is assigned to the current category while not that this category won’t get any information measure.
The config for this would be as follows:
#File Sharing
class-map match-all C2
match dscp C2
#Web
class-map match-all C3
match dscp C3
#FTP
class-map match-all C4
match dscp C4
policy-map QOS
class CS2

  1. List the all required hardware (Like but not limited to: Router, Switches), cabling, connectivity and the implementation.

Mainframes, Servers, Routers, Firewalls, Virtual Server, Data Center, File Server, FTP Server, Management Server, Mesh Topology Equipment, DB Server and Some Other Services & Basic Equipment. Cisco 6400/6500 Models are useful, Router C7200 & C3600, and ATM Switches. Estimated Cost Shouldn’t Be More Than Twenty Thousand Dollars.
