Hello Guys,
During the afternoon, put my methodology of studies that use to prepare me for the proof BCMSN (Building Converged Cisco Multilayer Switched Networks), 642-812. This will be the second test required to obtain the CCNP certification, and the first that I was the BSCI. The next evidence will be, respectively, ISCW and ONT.
Materials used:
Below the methodology.
- Structuring areas of knowledge for the content of the test. A good separation is used in the book of David Hucaby.
- Watch the video of the CBT Nuggets for area to be learned.
- Read the chapter on a surface to check the subjects attended in the video.
- Repeat steps 2 and 3 to complete the entire content.
- Try to practice some concepts relevant to Dynamips.
- Read the entire book in detail.
- Do laboratories of important topics.
- Perform simulations to obtain feedback of knowledge.
- Based on feedback practice or study more. Materials should be prioritized by external credibility.
- Repeat step 9 and 8 until the time the security in the study.
Extra Tip 1: After a detailed reading of the book, and start of practice, all questions that arise should be settled.
Extra Tip 2: For the BSCI I did a TXT which contained all my questions, they answered and other information that I felt needed to be fixed. Do it! It is a great way to fix something, because the amount of content is huge.
Following this approach want to optimize my time and learning. This method is based on previous experience I had with the other evidence.
A big hug and personal success for all.

Hello everybody,
In previous post I was informed that in the past BSCI and prontifiquei me to detail a little more of the day I had to get this certification.
First, the BSCI was my result:
Note: 911 / 1000
Trim: 790
Questions: 61
Time: 2 hours.
Scorecard:
- Implement EIGRP operations: 88%
- Implement multiarea OSPF operations: 80%
- Describe Integrated IS-IS: 85%
- Implement Cisco IOS routing features: 100%
- Implement BGP for enterprise ISP connectivity: 90%
- Implement multicast forwarding: 100%
- Implement IPv6: 62%
Confirm what many say, the BSCI is difficult! Ensures that all my preparation was not so good, would not in evidence. Unlike the CCNA, the BSCI has more questions that makes you think. In my test fell all content studied. Do not remember anything that did not fall.
The laboratories that fell in my test were:
- Troubleshooting a configuration of Virtual Link in OSPFv3;
- Bidirectional redistribution of IS-IS and EIGRP;
- Other than I remember …
The issues were the most diverse, so the rebound all:
Study and learn, because if you do not this (and try your luck for braindumps) may not be optimal and not pass the professional certification, as this evidence, especially, is Hardcore!
Each second of my journey of study paid off, because all I added knowledge. Now, talk a little as my preparation.
For the BSCI, I had not done any study plan - something that will do for BCMSN to optimize the time - but my study was to 24/03/2009 (the day after the approval of CCNA) until 30/05/2009 (2 days before being approved in BSCI) and followed by:
- I watched all the videos from CBT Nuggets by Jeremy Cioara (available in HD Blog).
- I made an overview of the book’s official CiscoPress by Brent Stewart (available in HD Blog).
- I started trying to practice some laboratories, but saw that something was missing.
- Li detail throughout the book of Brent Stewart, during the reading was practicing laboratories for each of the chapters that happening.
- After completion of the book, began my long journey in laboratories. Laboratories of all that I fell in BSCI, often mixing 2 or 3 areas of expertise to observe the convergence of protocols together.
- Began to address issues of simulated to identify my weaknesses.
- Identified these weaknesses, reread the chapter of the book, practicing with laboratories and when this issue was fairly safe as the content did a simuladão of this whole field.
- I was alternating between steps 6,7,8 until 1 week before the day of examination.
- Relax this last week, as was the feeling I could have done a week earlier. But that was not reviewed the 100% secure (Multicast) and 2 days before the test found a text named BSCI QuickSheat that was quite interesting to see the entire contents of the evidence as a general overview.
- One day before the test, relax and not seen anything of the content or annotations.
Extra Tips: Always keep a TXT annotations! When you have a question put it in TXT. When you have an information that is new to you write it in TXT. Thus, you have compiled a file of information and can track all your progress, and if the development of your study you have a question that relates to what you studied, you have noted in TXT.
Personnel, per hour is this. I hope to have contributed a lot, and now towards BCMSN. This week will draw up a plan of studies and will publish on the blog for you to follow.
A strong hug and success to all of us.

Hello Guys,
Throughout my studies for the CCNA certification, I had many facilities for the practical part. How did the current Cisco Netacad 2002 to 2004 with very good teachers could do much any kind of configuration, troubleshooting and more. All with actual devices.
What I see in some studies of routes for people to study by itself is a lack of practice in the intermediate period of study. In my view, this happens because of the difficulty in setting up scenarios and create from scratch.
In this post, I offer you a ‘package’ laboratories to the Packet Tracer which addresses various concepts by means of various topologies. But best of all is that the laboratory has already guide their goals through the configuration and / or troubleshooting.When you finish setting click Check Results to see the score and get a feedback from your configuration.
Below is the screen of the topology and order.
This package has several laboratories, but those used by me are available on the first link, the folder PT3.2Saves. In the second link, other laboratories are available. Some, besides having the basic file containing the answers made by me.
The file that has all the step by step to open is what is the extent PKA.
Follow the links to download:
Package of Step-by-step Labs for CCNA PT3.2Saves
Package of Step-by-step Labs for CCNA Others
Any questions please contact us.
A big hug and success to all!

Hello Guys,
I did this summary on the most important of IPv6 to be didactic, comprehensive and objective. The level of coverage of this summary would be midway between BSCI and CCNA certifications. Below.
IPv6
- We added several features compared to IPv4, such as 128 bits for addressing (IPv4 only 32), security (through extension headers), techniques to transition from IPv4 to IPv6, QOS embebbed (direct the header), Autoconfiguration ( allows a host to obtain an IP address without having to run DHCP on the network) and IP mobility.
- The IPv6 address has 128 bits and is divided into 8 ’sextet’, each with 16 bits.
- The Header (including the source and destination IP) has 320 bits, without the extensions - below.
- IPv6 does not have the checksum field (and not the place), considering that the control of errors of lower layers is reliable.
- IPv6 USA not broadcast, but multicasting. A broadcast can be simulated by sending a multicast address to the All-nodes, link-local scope (FF02:: 1).
- Loopback Address -:: 1 / 128 (IPv4 = 127.0.0.1). Address default-route -: 0 / 0 (IPv4 = 0.0.0.0 / 0).
- EUI-64: format derived from the MAC-address used to assign addresses Link-Local. You get the MAC address (48 bits), the hexadecimal number FFFE inserted in the middle of it and changed the first 2 bits (from 00 to 20), so the MAC 00eb.1234.3322 in EUI-64 format would be: 02eb: 12ff: fe34: 3322. Finally, adding the prefix for link-local addresses would: FE80:: 02eb: 12ff: fe34: 3322.
- Types of IPv6 addresses:
- Global Unicast: Identifies a single host on the Internet. Prefixes will be assigned to each organization (48 bits or less), as seen in the picture. The IANA defines the prefix for these prefixes like 2000:: / 3.
- Link-Local: Each interface receives one of these addresses. It is used for the devices on the same network to communicate without having to use the Global Unicast address. Use the prefix FE80:: / 10 + the EUI-64 format.
- Site-local. Single address within the scope of the organization, not routable on the Internet. Prefix: FEC0:: / 10.
- Multicast: Identified by prefix FF00:: / 8. The next 4 bits are flags, and the other 4 next define the scope of Multicast (shown below). Beside, a diagram of the range of scopes.
- 1 = Interface-local.
- 2 = link-local.
- 5 = site-local.
- 8 = Organization-local.
- E = Global.
- Anycast: A Global Unicast address assigned to more than one device, set it as anycast. Has as its route to the nearest anycast device. See below.
- IPv6 Hosts must meet at least the following addresses:
- Global Unicast and Anycast (2000:: / 3)
- Link-local (FE80:: / 10, by Autoconfiguration
- Loopback (:: 1 / 128)
- Multicast all-nodes (FF01:: 1 and FF02:: 1)
- Another group multicast assigned.
- Routers, and this answer should also respond in address:
- Anycast address of the subnet (the subnet address with the Interface ID - Host address - set to 0)
- All-Multicast routers (FF01:: 2, FF02:: 2, FF05:: 2)
- Groups defined by multicast routing protocols (if applicable). EIGRP for IPv6: FF02:: 10, OSPFv3: FF02:: 5 (all routers) and FF02:: 6 (only DR and BDR).
- The main forms of transition from IPv4 to IPv6 can be made through the Dual Stack (running both IPv4 and IPv6 to no longer have need for IPv4) and tunneling (encapsulate the IPv6 packet within an IPv4 packet - figure). For the tunneling is expected the prefix 2002:: / 16.

Hello everybody,
In the final stage of preparation for BSCI did a more succinct summary of the routing protocols that are part of the scope of this evidence. This summary aims to differentiate various details that are charged in BSCI, such as standard metric when a route is redistributed, terminology and much more. The routing protocols charged in the examination are:
- EIGRP
- OSPF multiarea
- Integrated IS-IS
- BGP in a non-transit AS.
It created a table in Excel which was converted to a figure. This appears a little lower down. Click the picture to download it in full.
Cheers,
Maurício.

Hello Guys,
I would like to inform you that today was the HD updated the blog.
Were inserted all books CiscoPress official to study for each of the CCNP tests. Moreover, were included as simulated (TKS and P4S) to recommend its use only to identify the weaknesses in their study.
Another interesting tool for the study that was included is the video Mentors! All are narrated by the author Jeremy Cioara. For all that is good understanding of English is a perfect tool for setting the contents read in books.
Follow the link for the HD blog:
