Free Cisco CCNA Training: OSPF Router Types
By Chris Bryant ⋅ July 14, 2008 ⋅ 2 comments
Get familiar with the different OSPF router types that you will be required to know for your CCNA exam. In this video we’ll go over the OSPF router types and how to identify which router type a router is.
Free Cisco CCNA Training: Default-Information Originate (Always?)
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
One of the main benefits of using OSPF (Open Shortest Path First) is that all of your routers will have a similar view of the network. However, there will be situations where you may not want all of your routers to have a full routing table. While the configuration of stub areas and total stub [...]
Free Cisco CCNA Training: Point-to-Point OSPF Networks
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
When two routers are connected through S1 interfaces, one of them has to act as the DCE, and the DCE has to supply the clock rate to the DTE. Thus, while connecting the two routers directly, various problems arise while configuring them. It is entirely possible that while configuring them, you have not properly identified [...]
Free Cisco CCNA Training: Advantages of OSPF
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
This video from my Cisco CCNA Training will help you understand the advantages of OSPF (Open Shortest Path First) over other types of protocols. Though you may not encounter these questions while undergoing the CCNA exam, these certainly will be useful if you have a job interview scheduled or the client asks you about it. [...]
Free Cisco CCNA Training: OSPF Authentication
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
OSPF authentication can either be done using clear text method or the MD5 method. This video primarily focuses on letting you know what commands need to be executed to set either type of authentication method. Though simple authentication is rarely used in the real world, you may be asked about it on your CCNA exam, [...]
Free Cisco CCNA Training: The OSPF Router ID (RID)
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
Numerically, the highest IP address is set as default OSPF Router ID (RID) by the system in a loopback interface. Now, in a physical interface, a number of things can go wrong. There might be a hardware error, or the cable connecting the routers might come loose or there might be a power cable problem. [...]
Free Cisco CCNA Training: Broadcast Networks
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
Broadcast networks are better suited for OSPF. Configuring an OSPF network is a tedious task since each router needs to communicate with the other by sending updates in order to create a topology table. If this does not happen then this topology table is not created or fabricated which can affect the overall stability of [...]

Free Cisco CCNA Training: How the Dijkstra Algorithm Assist with Loop Prevention
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
A big difference exists between a Distance Vector protocol, such as RIP, and a Linked State protocol, such as OSPF. In earlier training videos on Distance Vector protocol, you would have seen spilt horizon in action with some routes. Then we also saw what would happen if route poisoning did not exist. But we need [...]
Free Cisco CCNA Training: Neighbor Values
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
Hello and Dead intervals in an OSPF network determine the convergence speed of an OSPF network. At times it becomes necessary to adjust the intervals so that convergence time can be minimized. By default the Hello interval is set at 30 seconds and the Dead interval is set at 120 seconds. Now Hello and Dead [...]
Free Cisco CCNA Training: Troubleshooting Adjacency Issues
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
In a network configuration, for successful link-state exchanges, the fact that the routers employed are neighbors is not sufficient. These routers must be adjacent for the aforementioned exchange to occur. In other words, adjacency is an advanced neighborhood formed by the different routers amongst which a set of negotiating parameters control their willingness to exchange [...]
Free Cisco CCNA Training: Hello Packets
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
The function of Hello packets in an OSPF network is to discover its neighbors and to remind other routers that they are in a network. Hello packets are exchanged between the neighbors at regular and pre-determined intervals. For broadcast segments, this interval is of 10 seconds while for non-broadcast links, it is 30 seconds. Having [...]

Free Cisco CCNA Training: Link State Routing Protocol Concepts and Basics
By Chris Bryant ⋅ July 14, 2008 ⋅ Post a comment
Routing protocols are divided into two main classes: link-state routing protocol and distance-vector routing protocol. As you already know, in distance-vector routing protocol, for successful communication, each node shares its respective routing table with its adjoining neighbors. This leads to the consumption of a substantial amount of bandwidth, slow network response, and incites an unnecessary [...]
Free Cisco CCNA Training: Introduction to Open Shortest Path First

In this video, we will be looking at various different Open Shortest Path First (OSPF) types and will also be configuring the same by configuring and setting up the live equipment. After watching this video, you will be in possession of the knowledge that is necessary to pass the CCNA exam and configure the equipment [...]
Free Cisco CCNA Training: Floating Static Routes
By Chris Bryant ⋅ June 14, 2008 ⋅ Post a comment
Learning how to use and manipulate floating static routes is a critical step in order to become a competent networker and to do well on your CCNA certification exams. This video aims at covering valuable information related to floating static routes. The Method A floating static route is another type of static route, the difference [...]
Free Cisco CCNA Training: RIP Limitations and Timers
By Chris Bryant ⋅ June 14, 2008 ⋅ Post a comment
The main reason why Routing Information Protocol (RIP) is immensely popular is because of its simplicity. However, it is the simplicity of RIP which creates problems while configuring it. Though RIP works perfectly fine in most of cases, at times simple configuration mistakes and omissions leads to complex problems in a network that is difficult [...]
Free Cisco CCNA Training: The Joy of “show ip protocols”
By Chris Bryant ⋅ June 14, 2008 ⋅ Post a comment
To be completely aware of what you wish to accomplish is highly important, whether you are starting a task, or correcting the problems associated with it. In the case of networking, the same theory applies. Proper knowledge regarding how the routers are configured, whether a particular connection is experiencing issues, or a simple check of [...]

Free Cisco CCNA Training: Distance Vector Protocol Behavior – Split Horizon and Route Poisoning
By Chris Bryant ⋅ June 14, 2008 ⋅ Post a comment
When someone talks about packet-switched network theory, distance-vector routing protocol certainly encompasses a large portion of the conversation. Being one of the two major classes of routing protocols, in distance-vector routing protocols a router regularly informs its adjoining neighbors of the changes in topology. The other routing protocol, known as link-state protocol, instead exchanges only [...]
