Summary
This chapter provided an overview of the fundamentals of IP routing and IP switching and the control planes of operation. In summary, it showed how a router makes a forwarding decision, which consists of three basic components:
- The routing protocols, which are used to build the routing table (RIB)
- The routing table, which is used to program the switching mechanisms (that is, CEF)
- The switching mechanisms used to perform the actual packet forwarding
