Hello Guys,

Following my studies for the BSCI, the first of four tests of CCNP, presenting them to a lab that I understand the operation of the Integrated IS-IS protocol.

This protocol in the first instance seems to be complicated, but there is none. The difference is that it is based on OSI and not IP address in its origins. Another advantage is that it runs on the link layer.

The laboratory is based on a multi-area configuration that uses three devices and three other Level 1-2 Level 1 routing to internal areas. The topology is done in a Frame-relay multipoint network is seen as in the picture.

Was used to IOS c7200-mz.123-22.bin-ik9o3savailable in HD blog IOS folder.

Remember that you must change the paths of the IOS file. Net included. Also, it appears that the configuration in NVRAM of the router is successfully completed after the lab. If you want to start a new configuration using the configuration as TXTs base.

Hello Guys,

As I am studying for BSCI great summary of each routing protocols for IPv4.

One detail that should be noted that this was done in English resumão (: S). Believe staff, I can think better in English now, especially for the study. As the summary is presented in topics is interesting for all.

For those who are studying for the CCNA is interesting to give a brief look to see what is out there and enjoy some topics that are scope of certification.

A Abrasive,

Maurício.

Below:

Big Resume

EIGRP:
- Cisco proprietary and distance vector protocol (hybrid).
- Incremental updates.
- Uses Dual and crazy metric with K-values (1,3, Bw e DLY default)
- Establishes neighbors and mainting 3 tables (neighbor, topology, routing table).
- Neighbors must match: authentication, subnet, k-values, hello and dead timers.
- Only protocol that supports unequal cost load-balancing and backup routes (Feasible sucessor).
- If FS > AD the router can be a Feasible Sucessor.
- If there isn’t a feasible sucessor the router sends queryes for its neighbors asking for the route.
- Stuck-in-Active (SIA) is when a network is so big that it searches through it. To solve, router stub or summarization.
- Support ip summary address eigrp in the interface for summarizing the networks.
- Support keychain MD5 and plaintext authentication per interface.
- Support percentage of bandwidth usage, very used in PVC links.
- If you redistribute into EIGRP and don’t set a default-metric the route don’t to go to the routing table, because metric = infinite.»Continuar lendo Summary of Routing Protocols - EIGRP + OSPF + ISIS + BGP

Hello Guys,

After a series of technical problems faced and now 100%, with more bandwidth for the site and redundancy, I would like to contribute a collection of laboratories for the practice to the CCNA certification.

The following laboratories have been posted on the blog. A compilation was made to group all in a post that was created for the CCNA and have been made to the Packet Tracer, allowing playing them with just a double click on the file of the PT.

Below:

Laboratory Ripv2 - Configuration and practice of commands.
EIGRP Lab - Successor, FS and Topology table.
OSPF Lab - DR & BDR Convergence.
Laboratory STP (spanning Tree) - Convergence.
Frame Relay Lab - Setup, practice and learning of commands.
Laboratory VLAN Trunking - Trunking System and Identification of.

Remember the blog is available other laboratories, but focused on the professional level certification from Cisco, CCNP.

I hope it was a useful and available to me to answer any questions.

A Abrasive,

Maurício.

Hello Guys,

Step in our continuing study of BGP, make them a great picture that shows the choice of the best route in BGP, which is available in the book:

CCNP BSCI - Official Exam Certification Guide, 4th edition. Written by: Brent Steward.

The BGP is the protocol that has the highest metric! It uses attributes and metrics is enormous because it is composed of several of these attributes.

The attributes available to do the tuning of BGP are shown below.

Abrasive and a success in the study.

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 Guys,

To keep you informed of how my study is giving to the CCNP, starting with the proof BSCI, I have my list of chores to complete the study. The blog is also the few becoming a CCNP guide.

Today we finish the last of CBT Nuggets by Jeremy Cioara, and concludes that for the introduction of all concepts so easy and was very good. Now, it is necessary to establish the concepts and practice enough to stay in mind and more importantly, lead to career all that was learned.

I want to see the draft scheme that I needed to study the contents, because, unlike the CCNA certification where you can use the book of Mark, great source didactic content and very well explained for the CCNP books are those in which the CiscoPress content to me, is very sparse. It is placed muiiitos cases and artifacts that to my method of study just a little perplexed. I prefer to learn the concept, understand it and practice it to set well, but that is from each.

If you want to send any suggestions or bizarre scheme following this line hehehehe, very welcome.

Abrasive and a personal success for all!

Hello Guys,

This year I’m training, so the time passes very fast. I have to set my goals of the night pro day (it happened).

I decided that until the end of the year CCNP certified as me, then I’m already running behind.

The first part of the study will be reading the book CCNP BSCI - Official Exam Cert. Guide 4th edition by David Steward

After that, follow the same steps for the CCNA. Now, as this is the most complex use the CBT Nuggets more.

Below a picture of my set in note reading + Dynamips.

Embrace personal,

Success!

Maurício.

Hello Guys,

As can be seen, stopped updating the blog a bit, due to the fact that I am studying a lot to satisfy me until the beginning of April!

For all who wish to know the way in which I am organizing for the study below.

1. Read the book of Marco Filippeti CCNA 4.1.
2. Do laboratories routing (ACL, NAT, routing protocols, routes of learning …).
3. Do laboratory switching (VLAN, VTP, administration, Etherchannel, STP …).
4. Read for understanding the book of Mark and NetAcademy, parts of Switching and setting switches.
5. Do all TestKing from Switching.
6. Add a Pass4Sure for weaknesses.
7. Back to step 4 by reading what is identified as weak, and follow the sequence to identify that I am prepared.
8. Mark the event for maximum 3 days later.

This is my personal roadmap studies.

If you have any comments to one supplemented, or another suggestion, thank you very much involvement.

Abrasive,

Maurício.

Olá Pessoal,

Hoje, descobri um ótimo website para treinar o raciocínio rápido à respeito das VLSMs (Variable-lenght subnet masks). Ele apresenta diversas questões sobre endereçamento IP e máscaravas variadas, você pensa a resposta e clica para mostrar a resolução.

Vale a pena conferir.

Hello Guys,
I made a laboratory of switching a bit basic, but very interesting to identify the difference between links of access (switchport mode access) between VLANs and ‘junctions’ or trunking (switchport mode trunk). Below, follows the initial topology based switchesCisco Catalyst 2950.

Initial topology of the Laboratory Trunking

This lab shows the difference between using 3 links for access to move data between different VLANs, 3 switches and use only atrunk port for that. The Lab could be more prepared to put EtherChannels and then share the bandwidth of these 3 links, but what has is interesting.

This Lab was extracted from a ‘package’ with different laboratories: Link

Follow the link to the activity described containing the resolutions and the written Packettracer: VLAN Trunking Lab

Added routing between VLANs and VTP. VTP VLAN Trunking + + Routing between VLANs Lab

Abraços,

And success.
