Description

Dynamic routing protocols play an important role in the enterprise networks of today. There are several different protocols available, with each having its advantages and limitations. Protocols can be described and compared in regard to where they operate and how they operate. Three important characteristics that also influence routing protocol selection are convergence, support for summarization, and the ability to scale in larger environments. You can establish routing protocols over a variety of different network technologies. It is important to consider the limitations of a specific solution and how it affects routing protocol deployments and operation. To connect remote locations with the headquarters, you no longer need to use only traditional VPN solutions such as leased lines or Frame Relay connections. Newer technologies, such as MPLS VPNs and DMVPNs, are now widespread because they offer more flexibility at lower cost compared to traditional solutions. You should be aware of these new VPN types because they also influence deployments and the configuration of routing protocols.
|n This course begins with an overview of routing protocols that focuses on characteristics that describe their differences. It describes how limitations of different underlying technologies affect routing protocols, followed by a closer look at how Layer 2 and Layer 3 VPNs affect routing protocols. DMVPN is also introduced as a scalable VPN solution to complete this course.
