Summary

During the course of this chapter, we have discussed the strategies that Cisco IOS routers use to forward packets to their intended destinations. We looked at the routing table and broke down each component to give you a greater understanding of each component's purpose and responsibility on the router. You have learned how to predict the forwarding decision of a Cisco router in the following situations: when there are multiple routing protocols giving a route to the same destination network, when the same routing protocol has multiple paths to the same network, and when there are multiple paths with the same cost (metric).

I hope that this chapter has been informative and helps you on your journey toward learning how to implement and administrate Cisco solutions and prepare for the CCNA 200-301 certification. In the next chapter, Understanding Static and Dynamic Routing, we will learn how to set up static and dynamic routing protocols to ensure IP connectivity between...
