OSPF for Traffic Routing The OSPF dynamic routing protocol is probably the most popular LAN routing protocol today. OSPF can scale to the largest LANs but can also start out small. With OSPF, every router has its own unique "picture" (topology map) of the network. Routers use "HELLO" packets to periodically check with routers to ensure they are still there. Every router in OSPF is identified with a "router ID". The router ID can be manually entered or OSPF will automatically choose the IP address with the highest number. To configure OSPF,
Set the bandwidth on your interfaces using the bandwidth command Router (config-if)# bandwidth XX (where XX signifies the bandwidth of the WAN connection).
Router (config)# router ospf {process-ID#}
Next, instruct the router to advertise the networks that are directly linked to it by entering network statements with the area ID number for that network,
Router (config-router)# network {X.X.X.X} {Y.Y.Y.Y} area {z}
X.X.X.X = Network ID of Network
Y.Y.Y.Y = the wildcard mask for the network (the wildcard mask is the inverse mask of the subnet mask).
Z = the area ID number (For small networks, this can always be zero (0) but for larger networks, the area IDs need to be properly planned as all routing updates must traverse area 0).
You should enter a network statement for every network directly attached to the router.
Once OSPF is configured, you can check the status using the show ip route and show ip ospf commands.
Example
Here is an example of a router configured with the OSPF routing protocol using our router set up from last week.
Interface Gigabit Ethernet 0/0 ip address 182.62.00

Cis 532 Case Study 2

...Biology Lab is running RIP protocol, whereas the Fund-raising office is running OSPF routing protocol. The new Genome4U Lab network is decided to run on EIGRP routing protocol. The edge router of this network is used to redistribute the RIP, OSPF and EIGRP routes. It will also be used to provide internet access to the Genome4U Lab network through the University Campus Network. Network Design As shown in the figure below, the Biology lab network, fund-raising office network and the University Campus network would be connected to the edge router of Genome4U lab network. The Genome4U edge router would be running multiple routing protocols i.e. EIGRP for internal network, RIP for redistribution with Biology Lab network, OSPF for redistribution with Fund-raising office network. The interface facing the Biology lab network would be configured with RIP protocol, whereas the interface connected to the Fund-raising office network would be configured with OSPF protocol. The interface connected to the Genome4U lab network would be running EIGRP routing protocol. Redistribution will be configured in the edge router. RIP and OSPF will be redistributed into EIGRP LAN with two way redistribution i.e. the redistribution of routes will be done both ways, redistributing EIGRP routes into RIP and OSPF LAN and RIP, OSPF routes into EIGRP LAN. A default route will be added in this router to route all internet traffic to the University Campus Network for internet...

A Delay-Based Optimum Routing Protocol Scheme for Collision Avoidance Applications in Vanets

...Optimum Routing Protocol Scheme for Collision Avoidance Applications in VANETs Gayathri Narayanan1,a, Neethu Sathianadhan2,b and Sruthi Sanjiv Gangadharan3,c 1,2,3 Department of Electronics and Communication Engineering Amrita School of Engineering, Amritapuri Campus Kollam – Kerala, India agayathrin@am.amrita.edu, bneethu91ammu@gmail.com, csruti.sanjiv_g@ymail.com Keywords: Broadcast, Multi-hop, VANETs, Delay, Routing Protocols, AODV, Cluster-based routing, OSPF. Abstract — Broadcast transmissions are currently finding extensive applications in vehicular ad-hoc networks, albeit primarily in the research phase. Given the importance of knowing the updated network details of each node in the network, and also considering the fact that the delay in transmission of messages is a crucial factor in collision avoidance, it is imperative to implement a broadcast network which will ensure minimum delay in transmission of messages between the nodes. In this paper, we primarily implement a multi-hop broadcast vehicular network for collision avoidance. We consider the mobility and traffic density of vehicles and simulate the end-to-end delay in message transmission for a sparse and dense network scenario. In order to ensure high reliability and get the optimum delay, we extend the scenario to include three different routing protocols – AODV, Cluster-based routing and OSPF – and perform a comparison based on the end-to-end transmission delay to determine the optimum routing algorithm...

Eigr vs Ospf

...EIGRP vs OSPF IP Networking NT2640 Travis McCaig 05/07/16 Mr. M. G. Durazo Ed. EIGRP vs OSPF In this paper we will explore and compare EIGRP and OSPF protocols to determine if one might be better suited to a particular network. First I’ll explore their positive or negative features individually. Then I’ll do a more side-by-side comparison to see if there are more noticeable differences. Finally, I’ll make an informed decision on which protocol to choose based on network’s size, topology and more. EIGRP Enhanced Interior Gateway Routing Protocol or (EIGRP) is a protocol that lets routers exchange a copy of its neighbors routing tables. These tables are updated each time a new router comes online and EIGRP can detect changes in routes. It can do this marvelous feat by periodically sending a “hello” packet, that essentially responds an active or inactive result. If a router isn’t available EIGRP changes the route as well as updates the other neighboring routers. Finally, this protocol can consider distance and determine if a path is loop-free thereby determining most efficient route. OSPF Open Shortest Path First also called OSPF is a protocol that like EIGRP can exchange routing tables with neighbors with an added bonus. The bonus is that it creates a complete map of all networks and this is dubbed an Autonomous System or AS. This complete picture of the AS is also copied and shared but the advantage lies in the ability to manually manipulate routes for traffic engineering...

98-367 Sec. Fund. Chapter 4 Routing Essay Questions

...1. Describe the process of network routing. Routing is the process of moving packets across a network from one host to another. It is usually performed by dedicated devices called routers. Packets are the fundamental unit of information transport in all modern computer networks, and increasingly in other communications networks as well. They are transmitted over packet switched networks, which are networks on which each message (i.e., data that is transmitted) is cut up into a set of small segments prior to transmission. Each packet is then transmitted individually and can follow the same path or a different path to the common destination. Once all of the packets have arrived at the destination, they are automatically reassembled to recreate the original message. What OSI layer does a router work on? 3 or network. What type of address does a router use? IP address 2. What is a router hop? In computer networking, a hop is one portion of the path between source and destination. Data packets pass through bridges, routers and gateways on the way. Each time packets are passed to the next device, a hop occurs. Which protocol uses router hops? Routing Information Protocol (RIP). What is the maximum number of hops allowed? This limits the number of hops allowed in a path from source to destination. The maximum is 15, and 16 is deemed unreachable. The hop-count limit prevents routing loops from continuing indefinitely. Although, IGRP will route IP, IPX, Decnet and AppleTalk which...

Bellman – Ford | Dual algorithm could be in status, query out the whole network shortest path. | Protocol | USP | IP | Topology | Can build a hierarchical and scalable network. | Cannot build a hierarchical network with this protocol. | The Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance – vector routing protocol that is used on a computer network to help automate routing decisions and configuration. The protocol was designed by Cisco systems as a proprietary protocol, available only on Cisco routers, but Cisco converted it to an open standard in 2013. EIGRP allows a router to share information it knows about the network with neighboring routers within the same logical area known as an autonomous system. Contrary to other well known routing protocols such as routing information protocol, EIGRP only shares information that a neighboring router would not have, rather than sending all of its information. EIGRP is optimized to help reduce the workload of the router and the amount data that needs to be transmitted between routers. The features that support EIGRP are the following; support for Classless Inter-Domain Routing (CIDR) and variable length subnet masking. Routing is not summarized at the classful...

...Interior Gateway Routing Protocol. Though it adopts distance vector algorithm, it has some features of link state protocol. EIGRP has improved a lot compared to IGRP; it relies on the Diffused Update Algorithm (DUAL) to calculate the shortest path a destination within a network. It is totally loop-free, and has very fast convergence speed among all the routing protocols. EIGRP is an enhanced distance vector protocol, relying on the Diffused Update Algorithm (DUAL) to calculate the shortest path to a destination within a network. The strengths of EIGRP are Fast convergence EIGRP is an advance distance vector protocol, one of its core strengths is its fast network convergence capabilities, unlike other routing protocols EIGRP keeps feasible successor routes right into the routing table, and this allows millisecond convergence should the successor route fail. Flexible in summarization Unlike OSPF, EIGRP allows you to summarize anywhere, in bigger environments where routers are advertising hundreds of networks, route summarization can greatly enhance router's and network operational capabilities, its less taxing on CPU/memory and cheaper to run / maintain. Unequal cost load- balancing EIGRP allows unequal cost load balancing, which means you can use 2 different cost links to load balance traffic, no other protocol can do this. It is VLSM friendly unlike other distance vector protocols, and EIGRP supports VLSM and discontinued networks. EIGRP is also less confusing than OSPF because it does...
