Evolution of Network Switches and Routing Decisions

The chapter explores the journey of network switches from their initial configuration state to operational and forwarding states, emphasizing the speed and efficiency of processes like rib and fib routing. It discusses the historical advantages of MPLS over IP routing, the evolution of network devices, and the impact of specialized silicon like CAM tables on forwarding decisions. The debate on the placement of rib and fib in CPU or specialized hardware showcases the complexity of forwarding data in network devices.
