It is not just essential to understand the concepts of any routing protocol but also to know how to configure it. Understanding of configuration also helps in troubleshooting the network. In this post, we will go through a basic OSPF configuration for Single Area and Multi Area OSPF. Single Area OSPF Configuration OSPF (Open Shortest … Read more
OSPF, as we already know, is a Link- State routing protocol, and being a Link state routing protocol, each router in a network exchange information about the state of their directly connected links with all the routers in a network. It looks fine when we talk about a limited or small number of routers in … Read more
Before we dwell deep into multicast routing protocol, let us discuss the modes of transmission. Transmission of the packet can be done in three ways, namely- Unicast In the case of unicast, the packet is sent from one sender to one receiver, i.e., it is one-to-one communication. Broadcast In the case of broadcast, the message … Read more
A BGP router attaches BGP Attributes to various prefixes contained in its BGP update messages to define them. Except for update messages that contain just withdrawn routes, every update message has a different set of BGP properties. BGP attributes get classified into different types that define how routes will use and propagate a specific attribute … Read more
In this comprehensive blog, we will dive into the numerous types of memory observed in Cisco devices. Understanding the different memory types is critical for network administrators and engineers who work with various Cisco devices. We will also discover the in-depth reason and the functionality of each type of memory in Cisco devices, in addition … Read more
The moment we discuss technology, LAN and WAN are the two crucial aspects. The differences between LAN and WAN is what one should know before indulging in the in-depth concepts of tech. Thus, read the blog till the end to know the difference between the two better. What is LAN (Local Area Network)? LAN, … Read more
What is CDP in Networking? The Cisco Discovery Protocol (CDP) is a network protocol developed by Cisco Systems, which operates at the data link layer (Layer 2) of the OSI model. It is a Cisco proprietary protocol. CDP is used to collect information about nearby Cisco devices within a local network. CDP is used for network management. Cisco … Read more
The transmission Control protocol is connection-oriented protocol, and it ensures the proper delivery of data. To be a reliable protocol, it uses some extra data fields. This field is known as TCP Header. Whenever data is received to the transport layer, a header is attached to the data, which includes some important information that helps … Read more
We have a network design with one segment of LAN connected to another segment using a switch, as shown in the figure. The links connecting the two switches are of 100mbps bandwidth. Both LAN segments are communicating with each other and transmitting traffic, as given below- PC A sends 40Mbps traffic to PC D. PC … Read more
In our home network, we have a WIFI router (which acts as a gateway router). What if it incurs hardware failure or some service interruption? We can no longer access the internet. Right? Similarly, in an organization with a network design, there is just one gateway router helping every host in a LAN to connect … Read more
