With IP there are two Link-State protocols in use OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System). Both work in much the same way, but OSPF is more commonly used. This white paper examines OSPF synchronization. 

This paper outlines the things you must consider when thinking about the feasibility of replacing a WAN provider’s provider (P) and provider edge (PE) devices with routers. This paper examines these considerations in greater detail, to see where any potential problems might arise. 

In this white paper, we’ll discuss routing and routing protocols. Before we begin, let’s define what we mean by aroute. In common usage, a route is an entry in the IP routing table. 

This white paper will look at some techniques for improving the performance of Distance-Vector (D-V) routingprotocols, including some techniques used with D-V protocols to solve the looping problem, and to speedconvergence. 

Border Gateway Protocol (BGP) is a very complex routing protocol where the administrator can influence the route choice in more ways than with an interior gateway protocol. This white paper will provide you with a high level overview of interdomain routing with BGP. 

In this white paper, we are going to discuss the application of QoS to networks with media flows installed within them, such as voice and video. We'll see that it is very unnatural for voice to even exist on a data network, because it was never designed to do so.
