Chapter 3. Shared Memory Routers
This chapter covers the following key topics:
In the previous two chapters, we covered IOS’ basic architecture and switching methods in the abstract. To understand how IOS actually works, though, it’s helpful to see how it operates on a real router. Because IOS is so closely coupled to the hardware on which it runs, each implementation has its own platform-specific features.
This chapter examines a very basic IOS implementation—the one for a group of routers known collectively as shared memory routers. Shared memory routers consist of several products, including the Cisco ...
