Overview/Description Open Shortest Path First (OSPF) is one of the most commonly used IP routing protocols in today's networks. It is an open standard that is used by both enterprise and service provider networks. OSPF has several functions and five packet types to enable all OSPF information flow between routers. OSPF areas may be made up of different types of network links and it is vital that you know which ones are being used in order to properly configure OSPF. It is equally important to note that OSPF pays special attention to different network types, such as point-to-...

Overview/Description Routing updates compete with user data for bandwidth and router resources, yet routing updates are critical because they carry the information that routers need to make sound routing decisions. To ensure that a network operates efficiently, you must know how to control and tune routing updates. Since there is no one type of route filter that is appropriate for every situation, the more techniques that you have at your disposal, the better your chance of having a smooth, well-run network. Simple routing protocols work well for simple networks, but as networks grow and...

Overview/Description The Internet has become a vital resource in many organizations, and the Border Gateway Protocol (BGP) is an alternative to using default routes to control path selections. Before the connection of an enterprise network to an Internet service provider (ISP) can be implemented, planning needs to be completed. To plan for connectivity to an ISP properly, the network designer must take into account certain details. This course provides the knowledge required to implement enterprise-to-ISP connectivity. This includes an understanding of the types of session origination points...
