As a result of this configuration, the original packet from source IP 192. Adds any default routing information to the OSPFv3 updates. When R1 sends the BGP packet out to R2, it’s load balanced and is either going to go along the top path or the bottom path. Make sure your interface has a path to To configure SSH on Cisco router, you need to do: Enable SSH on Cisco router. Here’s an example: Router (config)# snmp-server contact David Davis – Network Admin – 555-1212 Router (config)# snmp-server location Dallas, Texas, USA Router (config)# snmp-server chassis-id. Practical Learning is a great way of learning as it aids to increase a learner’s interest in a certain subject.Cisco router configuration examples. It entails the use of visual aids to convey ideas even more effectively. Students can more easily understand and adapt the information from the subject, when they can visually see how it really works.

Rather than just explaining the theory concepts, using animating slides, simulation software that explain the theory concepts easily can be used by the instructor to develop the stu-dent’s skill in the particular subject. Simulation tools provide significant cost savings in Education. This is because a topic can be taught effectively to large numbers of people without the need of buying expensive equipment. Like wireless networking labs, if we want to construct the lab with the equipment like wireless router, access points, different cabling it is more cost effective. Now in net, we can find out more simulation software for networking. One of the best simulation tools for Networking is Packet Tracer which can be freely downloadable from Cisco Networking Academy Students. It includes assessment task with automatic scoring and reporting. This paper presents the features of the simulation tool and analyzes the student’s performance over this simulation soft-ware with the given questionnaires. This study provides evidence in support of the instructional effectiveness of the use of Simulation software tool for the teachers and the learners who are interested in networking concepts.Trblsht_netwk_conn_final.pkt: This Packet Tracer file contains the lab with the issues resolved. Troubleshooting is an art that requires great analytical skills and an understanding of how things work. We sometimes make the mistake of jumping into troubleshooting without first trying to understand the problem. As a result, we fumble about with different tools and methods in a brute-force manner instead of taking a step back to understand what is going on. That being said, there is no one-size-fits-all method for troubleshooting and the method you use will differ from scenario to scenario. For example, if you are dealing with Layer 3 (IP) forwarding, you probably want to start with understanding the traffic flow: How is traffic supposed to flow from device A to device B? When you’ve got this, then you want to start analyzing why traffic is not flowing that way for those devices and continue drilling down until you find the issue. On the other hand, if you are troubleshooting why two routers are not forming EIGRP neighbor adjacency, then you will use another method – one that is specific to EIGRP like checking K-values, and so on. When did this problem start? What changed on the network that could have caused the problem? In a real-world scenario, you will want to ask questions such as: The most basic troubleshooting scenario you will get as a network engineer is that a computer cannot connect to the network e.g., the user is unable to access some company resource or the Internet. It is always best not to assume that the user is really experiencing the issue and to see if you can replicate it yourself. In this type of scenario, you usually have access to the computer that is experiencing issues and one of the easiest things to kick your troubleshooting off with is Ping. Note: It is assumed that you have studied the lab setup and that you are familiar with the different IP addresses. Now we need to isolate whether the problem is with both devices or just one of them. One way we can do this is to test whether each device can reach any other device on the LAN (apart from each other). In our own case, another device on the LAN is the EDGE-RTR with IP address of 192.168.10.1 so let’s test from each device: Here we see that Host2 can access the EDGE-RTR but Host1 can’t. Since this is a network problem, what we can do is to check that the IP settings on the host are correct: This tells us that we can focus our efforts on Host1’s connectivity issue. Hint: On a Linux computer, you will use the ifconfig command instead of ipconfig. So Host1 has the correct IP address even though the default gateway is wrong.
