Trends in Campus Design


A large campus with groups of buildings can also use WAN technology to connect the buildings.
Although the wiring and protocols of a campus might be based on WAN technology, they do not
share the WAN constraint of the high cost of bandwidth. After the wire is installed, bandwidth is
inexpensive because the company owns the wires and [...]

Fill up a 100Mb link


1. To fill up a 100Mb link it would take approx 66 Frames of 1500 Bytes (1500 Bytes * 66 Frames / 1000 = 99Mb) each so does that mean that we can send 66 Frames per second on 100Mb and ~666 Frames per second on 1000Mb link.
Could you provide input on the following question [...]

why the 172.16 used widely ...where did ther idea spring from?


hey guys and gals ..i had to do alot of thinking to come up with this one..and i would personally like to know whowhay
are all the ip addresses with some routers and devies have the 172.16 ip address ..? who came up with this scheme.
just a question i pondered many nights beore going to bed

Configuring NAT, Frame Relay Simulation, and Access Control List


Instructions:
1. The Belfast router will perform NAT. Configure the Belfast router as
follows:
– Define the NAT pool, which consists of only one address. This is the
public address 192.168.1.6/30.
– Define an access control list, which will permit traffic from all internal
(172.16.0.0/24) addresses and deny all other traffic.
– Establish dynamic source translation, specifying the [...]

Case Study Deliverables


After the case study problem is solved, the network has been successfully
designed, and the prototype implemented and tested, you must provide a final
report to your instructor. This report should include thorough and well-organized
documentation of the process. We highly recommend that all tables be completed
using a spreadsheet program such as Microsoft Excel. Cisco Network Designer,
Visio, or [...]

Requirements


The preceding figure depicts the XYZ Research Company’s partially completed,
logical diagram of the required network. The company has also provided
networking equipment for development and demonstration. In some instances,
the equipment it provides does not have the required LAN interfaces. In this case,
the company allows configuration of loopback networks as alternatives.

Final Demonstration


The company requests a demonstration of the complete company inter-network. Configure all devices and access the Internet Server address from all networks shown. The company has selected the OSPF routing protocol with process ID of 50. Because the network is quite small, a single OSPF area is acceptable.
Record all configurations, routing tables, and outputs from [...]

Scenario


The XYZ Research Company is a small company that develops high-speed
wireless products. The main office occupies two buildings in Sydney; one
building is for the Administration Group, and the other building is for the Sales
and Marketing Group and the larger Research and Development Group. The
Research Group and the Sales and Marketing Group will each have employees
on [...]

Instructor Notes


Phase 1: Project Description
(This part can begin early in the semester, as students should be familiar with
subnetting)
The entire case study should be discussed in class so that all students understand
that the purpose of this study is not only to practice configuration and
troubleshooting, but also to learn how to document their work. Some good web
sites that [...]

Access Control lists


(This portion can be done after the chapter on ACLs.)
This is a most critical portion. Students must develop an access control list on
paper first.
Phase 5: Documenting the network
(If the students understand the requirements ahead of time, this part should be
done throughout the life of the case study. This would reiterate the purpose of
documentation – to [...]
