Summary
Throughout this chapter, we've discussed the roles and functions that ACLs play on an enterprise network. We also dived into discussing the operations of ACLs on a Cisco IOS router and how they are applied to an interface. Lastly, we covered both standard and extended ACLs and how they can be used in various situations.
Having completed this chapter, you have learned how to configure both standard and extended ACLs on a Cisco router. Furthermore, you have learned how ACLs function and filter traffic based on their ACEs.
I hope this chapter has been informative for you and that it will prove helpful in your journey toward learning how to implement and administrate Cisco solutions and prepare for the CCNA 200-301 certification. In the next chapter, Chapter 14, Implementing Layer 2 and Wireless Security, you will learn about various Layer 2 attacks and how to implement mitigation techniques and countermeasures.
