Summary

In this chapter, you have learned the importance of segmenting a network using VLANs to improve both network performance and security. You also now have the hands-on experience to create and assign VLANs, configure both access and trunk ports, and perform inter-VLAN routing on a Cisco network. You have gained the skills needed to implement and perform network discovery using the LLDP layer 2 protocol. Lastly, you have gained the knowledge and hands-on experience of merging physical interfaces into a single logical interface known as an EtherChannel.

I hope this chapter has been informative and helps you in your journey toward implementing and administrating Cisco solutions and preparing for the CCNA 200-301 certification. In the next chapter, Chapter 6, Understanding and Configuring Spanning-Tree, you will learn how to segment your network to improve performance and security and implement link aggregation technologies and discovery protocols.
