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.
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 [...]
The Open Shortest Path First (OSPF), as you already know, uses the link state routing algorithm and operates on a singular Autonomous System (AS). OSPF could very easily be the most widely accepted and used Interior Gateway Protocol (IGP), especially in large enterprise networks. Therefore, for being a successful networker, it is critical that you [...]
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. [...]
In case of an OSPF network, the connection between neighbors of a router can be authenticated. This allows for a more secure exchange of updated information. This video summarizes the various OSPF authentication techniques. There are two different ways to authenticate your OSPF network, the simple and the MD5 authentication. In the case of simple [...]
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. [...]
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 [...]
You already know that in distance-vector routing protocol, split horizon and route-poisoning are the two techniques which are used to prevent the formation of loops in the route under observation. This cannot happen in case of link-state protocols, because in this case, only the state of the node is exchanged, unlike distance-vector protocol where the [...]
