Hello Guys,

I created this article to compare the Packet Tracer 5.1 and Dynamips (using GNS3) associated with the use for the CCNA.

Each of these programs has its peculiarities, facilities and resources. I want to emphasize that these programs will be compared for their use in the certification CCNA, CCNP and then to recommend the following Dynamips without a doubt.

Packet Tracer

Officially, this software is available only to students of Netacad. In its version 5.1 software that makes the simulation of Cisco routers and switches. He is very good performance in question, as it does not perform the actual function of the equipment, but only simulated, not consume many resources of the machine, but does not provide all the commands of a router, many were destroyed. In the teaching aspect, the Packet Tracer is incredible! For all who are starting in the routing and the settings in yourSimulation mode, you can see the package or chassis / frame traveling from one device to another. Plus, if you click on the package as it passes through the devices you can see the whole process of (forward, discard, etc …) and the simulator tells you the stack of checks that it is to know where to forward the packet or frame ( check the routing table to verify NAT, NAT entry found, etc …). This information can be seen below.

Dynamips (GNS3)

While the PT is a simulator, the Dynamips is an emulator-only routers, or it gets the official IOS device and emulates in your machine. No question you have a router feature real in front could even bring it to route, linking the physical network adapter to the emulator. The full functionality of a router has a cost, processing and memory. You can emulate a 3600 router (IOS 12.3) with 64 MB of RAM, while a 7200 (IOS 12.4) needs to 128MB, not to mention the processing needed .. The Dynamips be suitable for all who know and routing and are well familiar with the route of a package based on the routing tables (and other details such as filter with ACL and etc …).

The GNS3 provides you the ease of designing your topology and turn it with Dynamips, similar to the Packet Tracer (to configure it to access Tutorial GNS3. Below is a screenshot of 4 running Dynamips routers 7200, each with 128, RAM allocated according to Laboratory IPv6 and OSPFv3.

Conclusion

The Packet Tracer, in my view, meet all the needs for setting the scope of the CCNA, through its simulator. Performs all functions without much cost of machinery, has an entire section which is important for teaching beginning and has a little more ease in time to create, or even import a laboratory.

The Dynamips is a complete platform, it emulates the device. You have full and unrestricted access to the IOS of the router, but you need a powerful machine. In the picture above was used a Core 2 Duo 1.8 Ghz w / 2GB of RAM. At the time of the bootstrapthe machine goes to 100% for a time to stabilize. If you want to do a short term level of professional certification from Cisco is interesting to use Dynamips to go testing and practicing a little more advanced commands and interface ‘real’ of a router.

For the CCNA, I am with Packet Tracer.

I hope this article has been very enlightening for all who have any doubt about which software to use the laboratories to achieve CCNA.

A strong hug personnel,

Hello Guys,

It is with great pleasure that I present them at first hand the result of my journey of study, the CCNA certificate.

I say part, because the certificate is only a small part of this experience that I added. Much of the knowledge I had was through the study to pass the certification.

I would like to dedicate this certificate to my parents and my brother when opened by hand view of what to study and mainly my girlfriend to see my dedication and support me all the time. I love you all!

This comment I made especially for all who are in quest for certification. Look at the certificate and see your name in this picture, because believe me, you will be the next!

Please note that the certificate only shows what you learned, therefore, study, practice and more than that … LEARN!

Always be here ready to assist them in any way.

Hello staff,

I want to move this post what should be done to get the best return and performance in CCNA.

Do not think that the psychological impact on its result not of proof, influences, but indirectly. If you are 3 weeks studying much, just sleeping, tired, stressed, your mind is tired and tense.

Below, I share the process I made a day before the test to allow a rest of mind and total relaxation.

How do I check the proof for Monday I had the whole Sunday to relax. On this day before the test take a time to relax with friends, chat, share ideas and express their happiness and affection with the next.

We gauchos do that taking a mate and chatter. You can be sure you know what causes the opening and to brainstorm ideas.

Go to a park or a square to admire the nature and be in harmony with everything: nature, friends, everyone. It feels good just has to add.

At night, relax and sleep early and always take a deep breath, because the nervousness catch fire!

In agreeing to take a bath and a good place for something that shows 0 do feel good! Well you are right! CCNA is just that you do not know that!

These words are to show them that if you study enough and feel ready, you should rest and stay in harmony, not to have to face the test, and yes, PASS the exam! Note the difference.

Professional success and especially, spiritual.

A hug staff,

Maurício Bento Ghem.

Hello staff,

It was a time I did not put any post on the CCNA due to my study to the next step, the CCNP.

This laboratory aims at setting the RipV2 several factors, such as passive-interfaces, in summary and self-routing.

I had never published any laboratory Rip, because I had a great understanding of the protocol and its operation, but due to demand and doubts that are past me, I am providing this laboratory for all seeking better their knowledge of distance-vector protocol .

Below is the link to download the laboratory:

Hello Guys,

This post is dedicated to all who would like to know exactly what needs to be a CCNA, what he does and the opportunity for the CCNA.

The information below was transcribed directly from Cisco’s website Syllabus. This website contains information on all certifications and skills gained from them.

The CCNA certification validate the ability to install, configure, operate, and troubleshoot medium-size routed and switched networks. CCNA certified professionals have the knowledge and skills to make connections to remote sites via a WAN, mitigate basic security threats, and understand the requirements for wireless network access. CCNA training covers (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2), VLANs, Ethernet, and access control lists (ACLs).

Source: Cisco CCNA Syllabus Website

I tried to create a version with translation Google Translator to lay more in English, but he accused the URL as invalid, so only in English.

In the same website you can follow all the other certifications and have an overview of the entire career in the Cisco and moths also have a goal for your career.

I hope it was useful for everyone, because I have much doubt that many of what exactly is a CCNA, and also what to do after achieving this title.

A Abrasive staff,

Success to everyone.

Hello Guys,

The key hit in my head this morning.

A firm commitment to help people who have the same goal that I, only I could achieve part of my goal.

I would now help you to get yours, so our goal CCNA Certification.

Through this post, I would leave a channel of contact for all who follow this blog to send me suggestions on topics that were in doubt on matters of evidence, psychological tips for preparation …

Anything you are interested in knowing who is in my power to help them.

Send any questions or suggestions to my email tópicospara, or if you wish add me on MSN.

Will the great pleasure to assist them.

Email: mauricio @ bentow. with. br

MSN: mbg_nh @ hotmail. with

I would also like to inform you that I have the goal of achieving the level of CCNP by the end of 2009. I will keep everyone informed about this new subject of study.

A Abrasive staff,

Success to us all.

Hello Guys,

Now I am CCNA certified, we will go to the next.

This tip goes to all who, like me, are on the way to CCNP certification (or above), or are tired of the Cisco Packet Tracer.

Is the installation and set-up package that already GNS3 install Dynamips and Dynagen to simulate a real Cisco router. The next image below:

Starting this tutorial GNS3

1. Please download the package of GNS3. In this package includes everything you will need to run the simulator. Available at:http://www.gns3.net/download.
2. Download the IOS will be used to emulate the corresponding Cisco router. In this case, we used the series in 2600, 3600 and 7200. IOS available, at your own risk, in: http://www.4shared.com/dir/7179596/e3a488a5/sharing.html
3. Installation is done like any Windows application, next -> next -> Finish.
4. Run the application.
5. Inside, you should include IOSs. Access the menu Edit -> IOS Images and supervisors in this screen, you should point the way to the IOS and set the model of router. Do this step for all who wish IOS.
6. Create the desired topology and press the play button to start all devices.
7. To connect to each one, click the right mouse button, and then Console.
8. In my case, I prefer to use Putty to manage the console. Then enter the menu Edit -> Preferences, General tab change the line start telnet% h% p by:
   

   start d: \ [localdoputty] \ putty.exe-telnet% h% p

I hope this tutorial helps you to create an initial scenario with Dynamips. Below are some interesting links that show many steps presented here through videos.

Hello staff,

Step in CISCO CCNA 640-802: DDD

I just post in the forum thread of Marco “I Passed the CCNA Exam” on my results in the CCNA 640-802 certification.

Below, write down my comment.

I spent today (23/03/2009) in the 640-802 CCNA Certification:

My note: 916

Note the cut: 825.

I had 2 hours to do the test because I did it in English but still missing when finished 47 minutes.

There were 44 questions.

Laboratories fell 2 configuration, 1 to show and answer the questions, 3 drags and drops, many questions on VLSM and rest the entire content. A question of IPv6 I split my face, no one knew me and thinning item.

On the study, I did the netacademy until 2006, and 640-801 did not passed. This year as I’m forming in college (computer Engineer) and I decided to pull the certification this year.

Studied from the book of Mark in January, the CCNA 4.1. Used as my main source of reference. My more specific questions were addressed by the book Netacademy and 3.1 of the 640-801 Wendell Odom. Some took questions in the forum. When I feel strongly I did some Tks to see my weaknesses and refiz the course of study to strengthen them (very good this strategy).

I made many laboratories related to EIGRP, OSPF, STP and others, all in PacketTracer. Dynamips not used the facility for an hour to analyze packet with PT 5.1.

Throughout my journey, I was providing summaries, tips, laboratories and many other materials in my blog: www.bentow.com.br

Now, start to look towards the CCNP. Thanks guys.

For all who want to follow my steps, I put down the address of my blog to continue keeping with materials for those who have the goal of passing the CCNA.

A Abrasive staff,

And that not Ferrugem says: “Together we are better.”

For all who meet the certification, you will receive a piece of feedback as those received by submitting a note on each topic of certification. Below:

Sheet 1

Sheet 2

Later I will do a detailed post on my path of study.

I am very grateful to everyone who contributed to this goal.

A Abrasive staff,

And no doubt I am very grateful to help.

Hello Guys,

I did this lab to understand how we can work the differences between the routing tables and topology of the EIGRP protocol.

The laboratory is to modify the bandwidth of links, to monitor the result on the topological and routing tables and check the convergence between them.

Download the lab with the settings used can be done here below:

Lab EIGRP - Successor and Feasible Successor

Below is a picture of the laboratory and instructions.

Hello staff,

With only a week for the big day, I’m practicing my very practical skills in areas I felt I needed a backup.

One of these was how the convergence of OSPF protocol in multi-access networks and the IDs of the routers with the choice ofDR and BDR on the network.

The laboratory has been done so you can see the convergence of the network when it on a modification.

Note that each multi-access segment has the election of a DR and / or BDR, so for the networks that have only one device, this will take only a DR and BDR no.

With respect to the Router ID, this is the largest IP interface in a logical (loopback). If there is a logical interface, the RID is defined as the highest IP address of an interface participating in the process of routing.

You can download them below:
