Hello Guys,

Last night completed the first phase of my study: to assist all CBT Nuggets concerning BCMSN exam following the book’s CiscoPress so superficial.

The next step, referring to my post in the methodology of studies and step 5, is the practice to get in Dynamips. As Dynamips is an emulator of Cisco routers, have to attach the module NM-16ESW that adds functions for switching the router.

After practicing some topologies, controls and other artifacts, will complete the reading of the book studies the official Cisco Press: 642-812 BCMSN 4th Edition, by David Hucaby.

A big hug,

Maurício Bento Ghem

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:

• 642-812 BCMSN 4th Edition, por David Hucaby. CiscoPress
• CBT Nuggets da BCMSN
• GNS3/Dynamips

Below the methodology.

1. Structuring areas of knowledge for the content of the test. A good separation is used in the book of David Hucaby.
2. Watch the video of the CBT Nuggets for area to be learned.
3. Read the chapter on a surface to check the subjects attended in the video.
4. Repeat steps 2 and 3 to complete the entire content.
5. Try to practice some concepts relevant to Dynamips.
6. Read the entire book in detail.
7. Do laboratories of important topics.
8. Perform simulations to obtain feedback of knowledge.
9. Based on feedback practice or study more. Materials should be prioritized by external credibility.
10. 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.

Maurício Bento Ghem.

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 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.

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 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.
