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,
More a summary of the series of commands show, now for the OSPF protocol with focus on the proof BSCI.
This summary was based on previously published lab: Laboratory OSPF and IS-IS with bidirectional Redistribution.
Below is a summary of each command. Each contains a link to its full output.
| COMMAND |
A RELATED |
RESULT |
| Show ip ospf [process-id] |
OSPF - General |
Displays details of configuring OSPF. Displays information such as: Router ID, timers, last performance of the SPF algorithm and statistics. |
| show ip ospf database [..] |
OSPF - LSAS |
Displays information of each type of LSA. Passing the parameter type is presented more detailed information on each. |
| show ip ospf border-routers |
OSPF - ABR / ASBR |
Shows the ABR and ASBR. Details as RouterID, interface connected and appear in this area command. |
| show ip ospf neighbor [detail] |
OSPF - Neighbors |
Presents a summary and status of the adjacency with its neighbors. This command displays information such as neighbor router ID, state (DR, BDR ..), dead time (time until the route goes out, or receives a new hello),IP address of the neighbor and the local router interface which is this neighbor. |
| show ip ospf interface brief |
OSPF - Summary |
Presents a summary of OSPF on each interface on which it is running.Shows: interface, process ID, area, and IP mask, cost, status (DR / BDR …). |
| show ip ospf virtual-links |
OSPF - Virtual-Links |
Displays (if applicable) the virtual-links and statistics. Information contained: Timers, Router ID, Area transit, state of the adjacency. |
| show ip route |
OSPF - Routes |
To illustrate that the router is redistributing the routes, is shown the command show ip route shows that both routes of Protocol OSPF and IS-IS (and the default route learned by the IS-IS). |

Hello Guys,
It is with great pride that I present a very interesting laboratory, following the original title of the Lab:
Laboratory OSPF and IS-IS redistribution with bidirectional and NSSA area with default-route, shown below.
With this lab was possible to acquire many skills, especially the redistribution of routes between protocols.
After some time trying to implement the optimal way for redistribution, or redistribute only the summary routes (hierarchical addressing was used), and finally it offers them the laboratory. Repair an area that was used ÑßÅ (not-so-stubby area) of OSPF to complicate the situation a little more.
Like all laboratories published by me, correct the paths in the. Net and grab the corresponding IOS in HD blog, IOS folder.Remember that to perform the laboratory from the start, or configure each device I provided the basic configuration files in TXT, and the final configuration is in the archives. Cfg in subfolder.
Also, follow the same recommendations for learning. Use and abuse of show and debug commands, modify the settings, put the links to check the convergence. Use this lab to learn.
Here is the link to download the laboratory:
Laboratory ISIS and OSPF Redistribution with bidirectional
No doubt, to feel the desire to contact me.

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 staff,
Communicating the commitment, I am creating the topology of my first lab in Dynamips (GNS3). Make it below as it is a very good model to work for several issues of OSPF multiárea.
I remember all to modify the file. Net to find the correct path of IOS used. In this lab, we used 3620 routers.
For those who do not know, multi-area OSPF is proof BSCI contents of the CCNP.
For anyone who may be getting anxious to appear only the content CCNP test, relax. Continue posting tips, manuals and CCNA labs this blog to help all who have the same goal that I make sure to Cisco. Now, rising more and more.

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:

Hello Guys,
Based on this laboratory for Frame-relay, I continue the list of commands Show. Now, trying to: routing, OSPF, NAT, and ACL.
Below shows a picture of the topology, and then show the commands based on it.
Topology of the Laboratory of Full-Frame Relay.
| COMMAND |
A RELATED |
RESULT |
| Show ip route |
Routing Table |
Displays the routing table. Shows the network in what was learned (dynamic or static) [administrative distance / metric] and IP and the interface on which this route was learned |
| Show ip protocols |
Routing Protocol |
Displays information from routing protocols running (summary and status). Information is given as specific details of each protocol (eg Router ID for OSPF), and advertising networks that are neighbors (source) routing. |
| Show ip ospf |
OSPF |
Displays the settings set to the OSPF protocol. Displays information such as: Router ID (the highest ID (IP) or the ID defined in the Loopback interface, if any) and timers. |
| show ip ospf data |
OSPF |
Displays now link the IDs, or the ID for each link (interface) has the time in which it was learned (age) and the link ID (ID of the interface of the router) that is advertising the route. |
| Show ip ospf interface <interface> |
OSPF |
Displays all information on each OSPF interface. Information such as IP address, OSPF area, Router ID, type of network (ppp, point-to-multipoint), information on DR / BDR (ppp links to the OSPF not elect DRs), timers and information about neighbors (vicinity). |
| Show ip ospf neighbor |
OSPF |
Presents a summary and status of the adjacency with its neighbors.This command displays information such as neighbor router ID, state (DR, BDR ..), dead time (time until the route goes out, or receives a newhello), IP address of the neighbor and the local router interface which is this neighbor. |
| Show ip nat translations |
