IPv6 Training (Cisco) – How to Enable EIGRPv6 on a Cisco Router

Now, some of you maybe wondering, why did he write an article on how to enable EIGRPv6 on a Cisco Router, when I already know how to do that?

Well, to answer your question, enabling EIGRP on a router that is running on an IPv6 network, is slightly different from enabling EIGRP on a router that is running on an IPv4 network.

Meaning, a router that is running on an IPv6 network, had EIGRP (EIGRPv6) enabled per interface, instead of globally like a router running on an IPv4 network would. So, in other words, when enabling EIGRPv6 on a Cisco router, you don’t need to use the “network” command when the router is in Router Configuration Mode.

Instead you’ll need to perform the following steps:

1. Router>enable
2. Router#configure terminal
3. Router(config)#ipv6 unicast-routing
4. Router(config)#interface type number
5. Router(config-if)#ipv6 enable
6. Router(config-if)#ipv6 eigrp as-number
7. Router(config-if)#no shutdown
8. Router(config-if)#ipv6 router eigrp as-number
9. Router(config-router)#router-id {ip-address | ipv6-address}
10. Router(config-router)#no shutdown
11. Router(config-router)#exit
12. Router(config)#exit
13. Router#copy run start

Steps Explained:

Step #1

1. Router>enable

Puts router into Privileged EXEC mode.

Step #2

2. Router#configure terminal

Puts router into Global configuration mode.

Step #3

3. Router(config)#ipv6 unicast-routing

Configures the router to route IPv6 packets

Step #4

4. Router(config)#interface fastethernet 0/0

Specifies the fastethernet 0/0 interface on which EIGRPv6 is to be configured.

Step #5

5. Router(config-if)#ipv6 enable

Enables IPv6 processing on the fastethernet 0/0 interface.

Step #6

6. Router(config-if)#ipv6 eigrp 1

Enables the EIGRP for IPv6 process on the fastethernet 0/0 interface.

Step #7

7. Router(config-if)#no shutdown

Starts the EIGRP for IPv6 protocol (process) without changing any per-interface configuration.

Step #8

8. Router(config-if)#ipv6 router eigrp 1

Puts the router into router configuration mode and creates an EIGRP for IPv6 routing process.

Step #9

9. Router(config-router)#router-id {ip-address | ipv6-address}

Enables the router to use a fixed router ID. (Remember each router Id must be unique)

Step #10

10. Router(config-router)#no shutdown

Put the EIGRPv6 routing process in “no shutdown” mode in order to start the EIGRPv6 process.

Technology in the Classroom – Ways to Integrate Educational Technology Into Your Teaching Practice

Here are some technology things that you could do with your students. Not everything may be feasible (i.e. cost factors) or appropriate (i.e. security or privacy issues):

some of the things we’re already doing,
some of the things we’re thinking of doing, and,
some of the things are simply wishful thinking, but great ideas have to start somewhere…
How do you integrate technology into the curriculum? Do you have any ideas to add to the list?

Class Set of Laptops

Get a company to donate a class set of laptops when they upgrade their equipment. (The company can receive a charitable donation tax-credit.)
Set up a wi-fi hotspot in your classroom so that students can blog online during independent reading and writing workshops.
Purchase digital copies of textbooks to have a paperless classroom. Use text-reading software (i.e. Kurzweil) to highlight and take notes in the textbook.

Non-Traditional Reading and Writing
Teach students the differences between formal, informal, and colloquial language and explore text messaging, chat rooms, and msn-speak as forms of colloquial language.
Evaluate the evolving nature of language and develop word-attack skills by examining how words get accepted into everyday language (or the dictionary). For example, Google is now a commonly used noun and verb.
Use text-reading software (i.e. Kurzweil) to allow students to access difficult texts.

Blogging
Have students set up personal blogs as a medium to publish their writing portfolios.
Explore how Google is a popularity contest. Publish work in an e-zine article directory to understand how to build inbound links. Post comments on other blogs to build inbound links.
Explore copyright issues. Publish work in a blog or an e-zine article directory will inevitably end up with your work scraped onto another blog without proper attribution. Explore how that feels and the ethics of using other people’s content without consent.

Computer Safety
Discuss cyber-bullying: ways to protect yourself, how to respond when it happens, and how to avoid accidentally cyber-bullying when blogging.
Explore computer safety: password strength, viruses, trojans, phishing, etc.
Learn about online dangers and ways to protect yourself.

Classroom Website
Make hand-outs and homework assignments accessible on a classroom website.
Use a secure website as a communication tool for marks for both parents and students.
Introduce your students to HTML and web design.

Making Money Online
Introduce students to the business of making money online.
Explore advertising online – how it works.
Fund raise by selling stuff on e-bay.

GPS and Mapping Technology
Geo-cache with your students.
Use GPS technology or mapping software (i.e. Google Earth) in math class to construct larger geometric shapes. (i.e. construct a circle that has a radius of 5 city blocks.)
Apply GPS technology or mapping software in Geography.

industrial machines for the 21st century

The 21st Century inherits much of the conveniences of industrial work from the discoveries and inventions made a century before. Computing and telecommunications technologies have seen some of its most furious pace of growth and development in the last 50 years. Miniaturization in electronics and data storage made these computers and telecoms gadgets not only small enough to be hand-held, but more powerful and affordable to the common man.

Aerospace and military sciences and engineering contributed much of the impetus to spearheading developments in these areas. And as a result, they have made inroads in the commercial industries that make life at home and work in the office a lot more productive and convenient.

Mainframes and Super Computers

Airlines and the aerospace industry have long been home to mainframe computers. These are highly robust computers that can do multiple tasks without suffering the problems found in our home and desktop PCs.

The requirements of the business often demand continuous availability of computing and networking resources. Only industrial-grade computers can fill this need. The last years of the 20th century saw the emergence of mini-computers that can work cost-effectively as departmental computers because of their specific highly focused computing resource, such as for accounting or purchasing functions.

They can be networked to enable seamless data access across the levels of the organization. But while they have achieved industrial-strength features, mainframes and super-computers have not lagged behind and they remain the staple computing resources in large industries and business complexes.

The global markets now confronting businesses have made mainframes the ideal core brain in large corporations. Super thinking computers that organize and process billions of data points are processed in parallel computers that can make up what are called super computers. The special effects in movies have moves the audience to expect nothing less than realistic visuals and sounds and the computers that process these images require so much computing power, like having a CPU for each screen pixel, that only massively parallel computers can do the job.

Robotics

This is a highly specialized computer application that is basically an output peripheral of powerful computers. Rather than having a printer as an output device, robotics employ mobile and agile armatures as output devices that can manipulate objects to achieve an end product or object. Automobile plants have these robots that can grab panel molds from forges, paint them and assemble with consistent precision humans would have difficulty achieving. And all these are controlled remotely from computers in an office.

Similarly, large warehouses with automated systems have robots installed along rails parallel to warehouse shelves and bins and controlled remotely from computers. These robots can sense the storage numbers and retrieve or pick up the needed parts or materials for distribution without the need for human intervention.

IPv6 Training (Cisco) – How to Convert Hexadecimal to Decimal

Steps:

Locate the “last digit” of the hexadecimal number that you want to convert. (the last digit of a hexadecimal number is the digit that is farthest to the right).
2. Once, you have identified the last digit; you will then multiply the “last digit” with (16^0). In other words, in step number two; you are going to multiply the value of the “last digit” with (16 to the power of zero).

Example: “last digit value” x (16^0) = “last digit value”

Note, that the power of 0 of any number is always 1.

Once, you have performed the formula on the last digit, write down the result; and then move on to the previous digit on the (your) left.

3. Each time you move on to a previous digit, you’ll need to increase the power (16^X) of the formula by 1 before performing the formula on that digit.

4. Simply perform the formula (digit value x (16^X) on all of the remaining digits until all digit results have been written down.

5. Then add (sum) all of the written down (stored) results together to get the final answer number.

Here’s an example: We are converting the HEXADECIMAL number FB8 to DECIMAL(the number 8 is the “last digit”)

8 x (16^0) = 8
B x (16^1) = 176
F x (16^2) = 3840
8 + 176 + 3840 = 4024

So, the decimal equivalent of the hexadecimal number FB8 is 4,024.

Here’s another example: We are converting the HEXADECIMAL number 7747 to DECIMAL (the number 7 is the “last digit”)

7 x (16^0) = 7
4 x (16^1) = 64
7 x (16^2) = 1792
7 x (16^3) = 28672
7 + 64 + 1792 + 28672 = 30535

life in a foreign country

The arrival of my wife and I, as legal immigrants, were full of good and high expectations in Phoenix, Arizona, USA. We felt in dismay for being not in accordance of what we have expected due to the recent recession. Getting settled here at this time of recession is quite untimely- mass layoffs, furloughs, businesses shutting down, home foreclosures, etc. Obviously, there would be stiff competition in employment. But this nation claims to be an equal opportunity employer- no discrimination regardless of age, sex, nationality, status, religion, etc. Where there is hope, there is a chance.

What You Should Ask a Copywriting Company Before Outsourcing Projects

Because there are so many organizations for intellectual property are willing to offer the kind of work you need can be quite difficult to know how to make a decision. Still, it must be rigorous and copywriting ask a series of questions before outsourcing their work.

A number of issues that we focus on. The idea behind the question is whether you are really looking for the right office and you understand what you read about them. But before we get to the questions is something we should have on hand.

Yes, you need to know your expectations right. We understand that your business needs, because with this knowledge, you will be able to make appropriate conclusions.

Question 1 – The guarantee your satisfaction?

It is very important that you can be assured of satisfaction. In other words, promising a quality job and we must not satisfied with the work that is not of good quality, so be sure and should be confirmed prior to award. You also need to know what to give as collateral.

the human race and artificial intelligence

Human beings are endowed with the most developed brain of all the species to ever inhabit this planet called the earth. This unique feature makes the humans to continually seek change and development. The ever lasting thirst of knowledge and to improve efficiency has led them to the discovery of artificial intelligence; the computer technology.

The computer or information technology has had a profound impact on almost all the aspects of the human life since its inception. Not only the social aspects are affected but also the financial ones too are profoundly influenced.

The computer technology which can be considered as a recent phenomenon when viewed on the scale of history of the world, has made progress in leaps and bounds in a matter of a mere decade or so. No one could have imagined the true affect of this emerging technology only a short while ago.

IPv6 Training (Cisco) – An EIGRPv6 – EIGRPv4 Overview

Now if you’re new to Cisco IT networking, you may not be totally sure about the EIGRPv6 protocol. I hope this article will quickly clarify things.

First of all, EIGRP stands for Enhanced Interior Gateway Routing Protocol; it’s the enhanced version of the Interior Gateway Routing Protocol (IGRP) and was created by Cisco Systems. Currently, there are two versions of EIGRP; version 4 (EIGRPv4) and version 6 (EIGRPv6); EIGRPv4 runs on IPv4 networks and EIGRPv6 runs on IPv6 networks. EIGRPv6 pretty much operates in the same manner as its predecessor EIGRPv4; and both versions of EIGRP do the following:

Allows an EIGRP router(s) to build a topology table from each of its neighbor’s advertisements; and then only the best routes from the topology table are placed into the router’s routing table. The best route to a particular destination is called a “successor” and the second best route to a particular destination is called a “feasible successor”.
Both versions of EIGRP, use the Diffusing Update Algorithm or (DUAL) for fast convergence and to guarantee loop-free operation.
Both versions of EIGRP, only send routing updates about paths that have changed, once an EIGRP network has converged.
Both versions of EIGRP, allow EIGRP router interfaces to send hello packets every 5 seconds on high bandwidth links and every 60 seconds on low bandwidth multipoint links to verify neighboring router connectivity.

The development of digital multimedia broadcasting

Satellite radio systems are actually part of a larger group of broadcasting mediums, which specialists refer to as Digital Multimedia Broadcasting or DMB. This digital transmission system is used in order to send data to different receivers such as radios, television sets or mobile phones and PDAs. There are two different ways of using digital multimedia broadcasting – S-DMB which is broadcasting via a satellite or T-DMB which uses terrestrial emitters. The complexity of the entire digital multimedia broadcasting field is huge. Out of all the features and characteristics digital broadcasting offers, satellite radio is probably the most spectacular as it generated immense interest and triggered an intense competition between the two main satellite radio broadcasters, Sirius and XM Radio. The development of satellite radio and other forms of digital broadcasting is spectacular because it offers two main qualities that terrestrial emitters are deficient in: quality and coverage. In the case of satellite radio, for example, the sound quality from a satellite broadcast is much higher than AM or FM broadcasts, as the hissing noises and transmission disturbances are eliminated.

Technical features of digital multimedia broadcasting – overview

Whether it refers to television, satellite radio or cell phone transmissions, digital multimedia broadcasting is based on the Eureka 147 DAB standard. Digital television uses the T-DMB which is made for transmissions on frequency bands III (VHF) and L (SHF). T-DMB is an ETSI standard (TS 102 427 and TS 102 428).
