Layer 3 – IP Routing Theory

FacebookTwitterGoogle+LinkedInEmail
Description
IP Routing Theory In this lesson we discuss several devices that serve the network layer, layer 3 and what functions those devices have.  You’ll learn the relationship between router and host and we’ll clarify what a host device on the network is. Through detailed diagram, you’ll see how a broadcast domain is configured between router and host, what the IP address naming convention in those relationships, and the importance of connectivity in placement for each configuration. We’ll also examine where/how proxy servers fit into this configuration and the how the transmission process flows differ for data packets that encounter proxies from those that don’t.
