Router and Switches II In Routers and Switches we learned several things such as: what is a Router, why we need Routers, what is the importance of a Router. We also learned what VLSM is and how to do it and use it. Throughout CCNA we learned how to configure a Router; the different types of Routing protocols and most importantly what, when and how to use those protocols in the field. Finally I will discuss Switches in how they are use to set up a LAN. Throughout this paper these topic will be discuss to cover what was learned through class lecture and text book (CCNA study guide by Lammle) and actually applied through hands on labs which were done with actual Cisco Router and Switches within a working LAN and Ethernet connection…show more content…
The most common of the two link state protocols is OSPF (Open Shortest Path First) it is widely used throughout the field (#1) due to it being a non proprietor protocol as well as its ability to interface with other networks. With OSPF you can group router into small areas and link them through a back bone when this is done you create the following a back bone router within the area of the back bone there is an area border router (ABR), ABR must have one interface in each area meaning the back bone and the area trying to link to the back bone, OSPF can also connect to multiple Autonomous System. When configuring OSPF you must assign a process number in all router within that group must use that same number, the number can range for 1 to 65,535 you can also have more than one each one will maintain its own separate topology table as well as manage it independently. There is also distance vectors RIP vs. 1 and 2 (Routing Information Protocol) these work well on small networks, IGRP (Interior Gateway Routing Protocol) and EIGRP (is the enhanced version of IGRP). The thing about these two meaning IGRP and EIGRP is that they are proprietary protocols so they only work
