Hello Guys,
Continuing the series of commands Show, presenting them to the IS-IS protocol.
This protocol is quite different from most because it is based on the OSI address. At first sight appears to be complicated, but understanding the theory behind the protocol is all uncomplicated.
Below.
| COMMAND |
A RELATED |
RESULT |
| show clns |
IS-IS - General |
Displays summary, include: number of interfaces that are running, NET timers and address. |
| show clns neighbors |
IS-IS - Neighbors |
Overview of neighbors. Include: remote router ID, interface, SNPA (link-layer address), status, and type of adjacency holdtime (Level-1, Level-2). |
| show clns neighbors detail |
IS-IS - Neighbors |
Presents details of the neighbors. Besides the above information still shows: IP address, uptime and area (from the NET). |
| show clns route |
IS-IS - Routes |

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,
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.
Below follows the link to download:

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,
The topic is covered in BSCI routing and is expanded including a new version of IP protocol, the IPv6. This new protocol will provide many more tens of IPs compared to IPv4 is used today.
The IPv6 for many (including me) is very obscure and complicated, but if you study with attention and practice quite calm through laboratories you understand its operation, including giants such addresses.
The laboratory that I am offering I did to practice addressing, summarization and working with the OSPFv3 (OSPF for IPv6).
I setup a Multi-area as can be seen in the picture attached and made a summarization of some subnets to see your reflection in the routing table and OSPF in the LSAS. Remember, the OSPFv3 differs slightly from its predecessor on the LSAS, so stay tuned.
As the oldest IOSs not support the OSPFv3 was necessary to use the IOS 12.4 (T) 9, the router 7200. The image is available on this link in the folder IOS - Dynamips.
Emphasize that the configuration in NVRAM of the router is complete, and after setting everything TXTs that are in the file is the initial configuration.

Hello Guys,
The blog following the flow of the author is also acquiring material for CCNP certification. Yesterday, continuing with the study Multicast finish my study and now started on the IPv6.
I contribute a laboratory that helped me in understanding the protocol PIM (Protocol independent Multicast) which is the protocol used in BSCI to create the routing tables multicast.
As there are two types of configuration of PIM, dense-mode and Sparse-mode, two laboratories were different and they both use the same topology (see Figure).
The laboratories are TXT files that are the initial settings. The settings are stored in NVRAM of router is the final, to be made tests. If you want to configure from scratch, feel at home. Below I provide them for download and use, pointing out that the router used is the 3600 with IOS 12.3 release 15 and download its IOS can be made in this link, paste IOS - Dynamips.
Download the laboratories can be made below:
Lab Multicast PIM-Dense Mode
Lab Multicast PIM Sparse-mode
Cheers,
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 Guys,
Continuing the initiative of the blog to be reference in the study of Cisco Certifications, now present a summary of messages and states of the BGP protocol.
Below.
BGP messages:
- Open: When the BGP process starts are established connections to TCP port 179 to the BGP OPEN message.
- KeepAlive: KeepAlive indicating that the connection is still established.
- Update: update network messages. Sent early in the process and when updates occur on the network.
- Notification: When a neighbor restart Notification is sent a message indicating that the relationship is ending.
BGP states:
- Idle - Seeking neighbors.
- Connect - TCP connection established with neighbor
- Open Sent - BGP OPEN message sent
- Open Confirm - Response received
- Established - BGP neighbor Connection established.
Troubleshooting
- Established is good, rest is the problem.
- If the neighboring state of not progressing to Idle, verify that the next-hop is achievable.
- If the neighbor is in state Active is not configured or is not behaving as expected.
- Make sure the neighbor is correct: IP addresses, Autonomous System (AS), configuration and authentication.
A hug staff,
Maurício.

Hello staff,
I like young and full of ideas available like to join the fun, work and study. I learned in college that the addition of these three tasks is called the creative leisure.
I am full of tasks to perform for college and was related to innovate a bit, I decided install my notebook on a monitor a little more topping. Yeah, and if I say that topping is nothing less than 40 inches (look in the photo)? hehehehe
