GRE
(Generic Routing Encapsulation)
Generic Routing Encapsulation (GRE) is a tunneling protocol used to encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an IP network. GRE is commonly used in VPNs and network virtualization to connect disparate networks securely.
GRE provides a simple and flexible way to transport data between networks, supporting multiple protocols like IPv4, IPv6, and MPLS. While GRE does not include encryption, it is often used in conjunction with IPSec to provide secure communication. GRE is widely adopted in enterprise networks for its versatility and ease of implementation.
