What is GRE?
Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network. It is commonly used to create VPNs or to transport non-IP protocols over IP networks. GRE is often used in conjunction with IPsec to provide secure VPN connections.
What other technologies are related to GRE?
GRE Competitor Technologies
DMVPN
DMVPN provides a similar solution to GRE with IPSEC for creating dynamic VPN tunnels, but offers more advanced features and scalability. DMVPN handles key exchange automatically, unlike GRE with manual configurations.
MPLS
MPLS is an alternative tunneling protocol that offers traffic engineering and QoS capabilities, often used instead of GRE for more complex networks. It provides similar connectivity without IP overhead.

Next Generation Multicast VPN, like DMVPN and MPLS, provides more advanced VPN capabilities compared to basic GRE tunnels. It offers better scalability and multicast support.
SSL VPN
SSL VPNs provide secure remote access, offering an alternative to GRE tunnels, often with easier configuration and broader client support.
VXLAN
VXLAN is an overlay network technology that provides similar tunneling functionality to GRE, but with better scalability and support for multi-tenancy.

GRE Complementary Technologies
IPSEC
IPSEC can be used to provide secure tunnels over GRE tunnels. It is often used with GRE to provide confidentiality and authentication.
BGP
BGP can be used to route traffic over GRE tunnels. GRE provides the transport, while BGP makes routing decisions.
OSPF
OSPF is a routing protocol that can be used to route traffic over GRE tunnels. GRE provides the transport, OSPF provides routing.
