GRE is used when packets need to be sent from one network to another over the internet. GRE tunnel is an encapsulation protocol and does not perform any encryption. When we create a GRE point-to-point tunnel without any encryption is extremely risky as sensitive data can easily be extracting from the tunnel and misused by others. GRE. Generic Routing Encapsulation (GRE) is a tunneling protocol that was first developed by Cisco. It can encapsulate a wide variety of network layer protocols within virtual point-to-point or point to multipoint links over an IP network. Some characteristics of a GRE tunnel include: supports multicast; has no inherent security features Protocol Types GRE uses an ETHER Type for the Protocol Type. New ETHER TYPES are assigned by Xerox Systems Institute [RFC1700]. 8. Acknowledgments This document is derived from the original ideas of the authors of RFC 1701 and RFC 1702. Hitoshi Asaeda, Scott Bradner, Randy Bush, Brian Carpenter, Bill Fenner, Andy Malis, Thomas Narten, Dave Generic routing encapsulation or GRE is a protocol that encapsulates packets of one network protocol, such as IPv4, IPv6, IPX, etc., within the payload of another protocol, like IP. The term "encapsulate" refers to the process of wrapping one data packet within another data packet.
