Aug 08, 2018 · If this tunnel were to be changed to a multipoint GRE (mGRE) tunnel, then all that is required for the tunnel to be in an up state is a valid tunnel source (an mGRE tunnel can have many tunnel destinations, so that cannot be used to control the tunnel interface state):
Site-to-Site VPN tunnel options for your Site-to-Site VPN You use a Site-to-Site VPN connection to connect your remote network to a VPC. Each Site-to-Site VPN connection has two tunnels, with each tunnel using a unique virtual private gateway public IP address. It is important to configure both tunnels for redundancy. When one tunnel becomes unavailable (for example, down for maintenance), network traffic is automatically routed to the available GRE over IPSec VPN Tunnel –VPN Failover — Zyxel Jul 04, 2019 GRE (3.4) > Branch Connections | Cisco Press

We want to use VPN I'm a little confused when to use a GRE tunnel and when to just use a simple VPN with IPSec tunnel. For example, I have a development network (192.168.0.0/24) that I need to encrypt the traffic using IPSec, then tranport it over a 10.0.0.0/24 network. The 10.0.0.0/24 network can not see the 192.168..0/24 in it's forwarding table. In the article “How to Configure a GRE Tunnel?” we talked about what tunneling is and how to configure a GRE Tunnel…In this article we continue to say something about the GRE tunnel and IPsec tunnel—what are the differences? Encapsulating a packet for secure transportation on the network can be done using either GRE or IPsec protocols. Aug 23, 2018 · #GRE (Generic Routing Encapsulation) tunnels are one of the most versatile tools available to a network engineer. They are a #VPN that can be used to tunnel through the internet,
Mar 26, 2018 · MikroTik provides GRE (Generic Routing Encapsulation) tunnel that is used to create a site to site VPN tunnel. GRE tunneling protocol which can encapsulate a wide variety of protocols creating a virtual point-to-point link was originally developed by Cisco. GRE is a stateless tunnel like EoIP and IPIP. That means if the remote end of the tunnel
CCNA Training » GRE Tunnel Tutorial Apr 26, 2018 Cisco GRE and IPSec - GRE over IPSec - Selecting and GRE Tunnels are very common amongst VPN implementations thanks to their simplicity and ease of configuration. With broadcasting and multicasting support, as opposed to pure IPSec VPNs, they tend to be the number one engineers' choice, especially when routing protocols are used amongst sites. Solved: GRE Tunnel - Check Point CheckMates Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets in order to route other protocols over IP networks. GRE is defined by RFC 2784. GRE was developed as a tunneling tool meant to carry any OSI Layer 3 protocol over an IP network. GRE Tunnel between Cisco and DrayTek Router | DrayTek
