OSPF is a classless protocol and allows a hierarchical design with VLSM and route summarization. The features of OSPF are as follows :- It was developed by IETF Open standard protocol, not Cisco proprietary It is the successor of RIP Uses SPF algorithm developed by Edgar Dijkstra Link state routing protocol Autonomous systems are divided into multiple areas for easy and efficient routing Classless routing protocol Works with Link state Advertisements Updates are through Multicast (224.0.0.5) Hello packets are sent every 10 secs Hierarchical design with Multiple areas Area 0 is called the backbone area Functioning of OSPF:- Unlike RIP, which broad...

The term is most commonly associated with  data networking   to describe the capability of a network to 'route around' damage, such as loss of a node or a connection between nodes, so long as other path choices are available. Dynamic  routing allows as many routes as possible to remain valid in response to the change. Systems that do not implement dynamic routing are described as using static router, where routes through a network are described by fixed paths. A change, such as the loss of a node, ...

Static routing can also be used in stub networks , or to provide a gateway o f  last. Static Routing use forme small organization only (5 to 7) Router canect. This routing data connection half duplex. is show the dynamic router. Configuring Static Router:- What is Static rout...

Marks:- 10+1 Name of student: Subhendu Pal Faculty Name: Priya Sawant  Roll No: 1503 Date: 22-01-2018 Session Name: Basic Router Routing Fundamentals Routing :-  Routing is a process by which a packet gets transferred from 1Network to outher Network. Destination IP Address Out interface (egress) Next Hop Concept   A router cannot transfer packets to the destination network as it should unless the network is directly connected to the router. This means that a router sends the packet to the next router on the best path to the destination. the next router is called the next hop. Routing Ways:- There are 4 ways to control routing decisions and enable the router to select the next hop:- i) Connected Network: -  When you want to route packets between two networks, a router is used.In this case, both of the networks are directly connected to router's interface. ii) Static routes :-  In Static routing, the routes are configured manua...

In order to communicate over the internet, computers and devices must have an IP address(sender & receiver) consider a situation where you are required to locate or communicate to a friend. Typical approach will be to look for the friend's address(it could be a postal address, email id or phone no.) Similarly, in the networking world, two important addresses. IPV4 Addressing :-  A 32 bit IP address often depicted as dot address. And it is grouped 8 bits at a time. If you look your PC's IP address you can see 4 parts of numbers separated by dots, something like 124.187.1.3 and those each number separated by the dots is of 8 bits. Each group of 8 bits is called an octet. This IPV4 class is 5 & small the IPV6. Classification of IP address Class A :-  class ra...

Etherchannel Terms :- Portchannel:- When multiple links are grouped into one single logical Port, it is know as a Port channel. Channel Group:- To configure and assign a physical interface to etherchannel, channel Group command are used Confirmation and Verifying Ether Channels Two types of LACP :- 1.  Active Mode:- it initates the negotiation and tries to form a channel Group' etherchannel' with the other end 2. Passive Mode:- it does not start link aggregation or packet negotiation. Two types of PAgP channel modes:- 1. Desirable 2.

The frames will be discarded on arriving at that port and this port will not learn any MAC address. Listening : The port in the listening state can send and receive the BPDU frames. However, listening ports do not forward any incoming frames. They also do not learn any MAC address. Learning : The port in the learning state already identifies its state in the STP domain.It will be learning the MAC address from the frames arriving at the port in order to populate the MAC address table. Forwarding : The port in the forwarding state will forward all Ethernet traffic as per the switch operation. Also, the port will process all incoming frames and wil...

Marks:- 10+10+3 Name of student: Subhendu Pal Faculty Name: Priya Sawant  Roll No: 1503 Date: 11-1-2018 Session Name:  Layer-3 Switching/ STP/ STP Port States Layer 3 Switch:- A network switch is a multiport network bridge that uses hardware addresses to process and forward data at the data link layer (layer 2) of the OSI model. Some switches can also process data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches. STP:- Spanning Tree Protocol (STP) is a network protocol designed to prevent layer 2 loops. It is standardized as IEEE 802.D protocol. STP blocks some ports on switches with redundant links to prevent broadcast storms and ensure loop-free topology. With STP in place, you can have redundant links between switches to provide redundancy Switching loops create 3 :- Broadcast storms :- A broadcast storm occurs when a switch is over...
