Tunneling and VXLAN in Networking

This chapter explores tunneling in networking, emphasizing its role in overcoming limitations of traditional routing methods and private IP addressing. It discusses the significance of Virtual Extensible LAN (VXLAN) technology in enhancing network scalability, security, and observability, while elucidating the relationship between overlays and underlays. Additionally, it touches on the complexities of Software-defined WAN (SD-WAN) and the innovative solutions provided by modern tunneling techniques.
