2014-2-21  The GRE tunnel itself is configured using a Tunnel interface. No IP address is configured but the tunnel source and destination are defined. The Loopback0 interface is used as the tunnel source and an IP address is provided for the tunnel destination.

gre_tunnel [Frantech/BuyVM Wiki]

2016-6-2  What is a GRE tunnel? Much like a proxy, a GRE tunnel allows you to pass traffic from your BuyVM VPS including DDoS filtering to another remote destination. GRE tunnels allow all traffic through, not just HTTP. With a GRE tunnel you can serve, and deliver any type of content from any type of server (audio, FTP, SSH, SCP, video, etc.).

如何在Linux环境创建GRE Tunnel_chuanzhilong的博客

2016-12-14  GRE tunnels are IP-over-IP tunnels which can encapsulate IPv4/IPv6 and unicast/multicast traffic. To create a GRE tunnel on Linux, you need ip_gre kernel module, which is GRE over IPv4 tunneling driver. So first make sure that ip_gre is loaded.

GRE Tunnel Overview Palo Alto Networks

2021-4-12  GRE tunnels are simple to use and often the tunneling protocol of choice for point-to-point connectivity, especially to services in the cloud or to partner networks. Create a GRE tunnel when you want to direct packets that are destined for an IP address to take a certain point-to-point path, for example to a cloud-based proxy or to a partner

Guidelines and Limitations for Configuring GRE Tunneling The following are some of the limitations pertaining to GRE tunneling on Cisco IOS XE Release Denali 16.3.1:

GRE Tunneling Support Palo Alto Networks

2020-11-3  GRE Tunneling Support The firewall can terminate a generic routing encapsulation (GRE) tunnel to connect two endpoints in a point-to-point, logical link. Palo Alto Networks next-generation firewalls can now terminate generic routing encapsulation (GRE) tunnels, which enables you to route or forward packets to a GRE tunnel.

Configuring GRE Tunnel Interfaces Tunnel and Encryption

2021-4-18  Generic routing encapsulation (GRE) provides a private, secure path for transporting packets through an otherwise public network by encapsulating (or tunneling) the packets.

Configuring GRE Tunnels arubanetworks

Layer-2 GRE tunnels allow you to have the same VLAN in multiple locations (separated by a Layer-3 network) and be connected. The forwarding method for a Layer-2 GRE tunnel is bridging. However, the drawback of using Layer-2 GRE tunnels is that all broadcasts are flooded through the tunnel,

How to configure a GRE tunnel Cisco Community

2009-6-22  Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses IP as the transport protocol and can be used for carrying many different passenger protocols. The tunnels behave as virtual point-to-point links that have two endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.

Configuring GRE Tunnel Through a Cisco ASA Firewall

The GRE tunnel will be terminated between routers R1 and R2. When configuring GRE, a virtual Layer3 “Tunnel Interface” must be created. The GRE tunnel will be running between the two Tunnel Interfaces (10.0.0.1 and 10.0.0.2 as shown from diagram).

GRE Tunnels Network Direction

GRE is not the only method of tunnelling, but it does have some advantages over some other technologies. For one, it is defined in RFC2784, so any vendor can support it. Also, it supports multicast packets, which means it can be used with dynamic routing protocols (unlike IPSec tunnels for example).
