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:

Any questions please contact us.

A big hug and success to all!

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,

This laboratory includes several areas of knowledge of routing. The basic configuration is shown in figure below.

In this lab the R2 router acts as DHCP server for your own network to network R3 using the command ip helper-address to use the pool set in R2.

The objective of this lab, and understand the DHCP configuration is able to observe the drop links and topology table to see the routes going to the active state, or seeking an alternate path for the route that fell.

Note that as in Dynamips is not possible to add hosts, routers only have added that without the function of routing. This was possible through the command ip routing.

In addition, follow the recommendations of all: show and debug commands and customize the labs to understand and learn. We used 3600 routers and IOS is available in HD blog. Do not forget to change the paths in the file. Net.

Here is the link to download.

EIGRP Lab - Practice and Queries Dhcp-Relay

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.

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,

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.

A Abrasive staff,

Maurício.

Hello staff,

Complementing my studies (and of you) on the conceptual part of the EIGRP below:

Regarding routes:

• Successor route: Route to a major destination. Is shown in the command show ip route andshow ip route EIGRP topology as successor.
• Feasible Successor: A possible alternative route to a destination. Presented in the table of topology and only goes into the routing table when a successor route becomes unreachable, or has a cost greater than the FS.

With respect to metric (cost)

• Feasible Distance: Distance calculated to a destination. It is composed of the reported distance + the calculated cost to the destination.
• Reported Distance (Distance advertised): Distance advertised by a neighbor router to a destination. This metric will always be smaller than the Feasible distance (as if more is going on a routing loop).

Here is the demonstration of these concepts.

Hello Guys,

The staff of the forum blog.ccna.com.br / forum posted a link containing several summaries of excellent quality, calledcheatsheets, written by the staff of the site Life Packet which includes several topics that are scope of CCNA. Below, shows the direct links for each of these cheatsheets.

Access-Lists, EIGRP, IPv6, OSPF, spanning-tree, Subnetting, VLAN, Wireless 802.11

Hello Guys,

Based on the laboratory of Frame-Relay published earlier in this post and after all the study of topology tergiversation the commands below, put their exits and made a table with a full description of what each line offers. There is a link that leads directly in charge for their output.

I hope that is good use of this table, because I use.

A Abrasive staff.

Hello Guys,

It is with great pleasure that I am posting this complete lab, developed to the satisfaction txt files including the configuration of each router and switch, Frame Relay and Packet Tracer file.

Continuing.

This laboratory consists of a matrix that provides internet to the other branches each connected by a link point-to-point to this, as in figure below:

Topology of the Laboratory of Full-Frame Relay.

The artifacts implemented in this laboratory:

• Creating Frame-Relay cloud allowing a virtual circuit in the link layer.
• Uses the protocol to EIGRP redistribution of enabling a default route complete communication throughout the mesh.
• Used with NAT Overload (PAT) allowing access to ‘Internet’.

The following artifacts could have been implemented to further illustrate a more realistic scenario and organizational:

• DHCP service to provide to the matrix hosts (PCs) assigned IPs dynamically.
• DNS service in the matrix providing translation of names.

Items to enjoy in this laboratory:

• How the Frame-relay encapsulates the frames (frames) and understand the role of cloud and the various components.
• Check the learning of the EIGRP routes through the various show commands available.
• Check the surroundings using the protocol CDP (Cisco Discovery Protocol).
  
• Check the settings for each of the equipment (Switch, Frame Relay, Routing Matrix and the Subsidiaries).
• Absorb the concepts after this lab.
• And do not forget, creativity is the limit. Modify, ask and let me know what you think of this laboratory.

I personally believe that is. I hope you enjoy the lab, because I am.

As my goal is to get the CCNA, this lab includes various interesting concepts in a case about the real world.

A Abrasive,

Maurício.
