description GRE Tunneling Overview
Generic Routing Encapsulation (GRE) is a tunneling protocol used to encapsulate a network layer protocol within another. While not a VPN itself, it is often used *underneath* a VPN or tunneling solution to carry non-IP traffic or to simplify routing across complex network boundaries. It requires a separate encryption layer (like IPsec) to be secure, making it a foundational networking tool rather than a standalone VPN solution.
