Generic Routing Encapsulation (GRE) is a software protocol that is used for encapsulating and transporting different types of network traffic between two endpoints over an IP network. It is commonly used for creating virtual private networks (VPN) and for connecting remote networks over the internet. GRE allows for the creation of virtual point-to-point links between different network devices and provides a way to encapsulate multiple protocols into a single packet for efficient transmission over the internet. The protocol is often used by network administrators to secure and manage network traffic as it passes over public networks.
