GRE
Starting from R81.10.07, you can create a GRE (Generic Routing Encapsulation) tunnel as a LAN interface
connected with a remote peer and route all traffic between the two sites.
Each site has its own routable physical IP address. The GRE tunnel is created on top of a physical network
interface, and each tunnel side is assigned a tunnel IP address which is different than the physical IP
address.
Notes:
n
Because the GRE tunnel connects two remote sites over the internet, Quantum Spark
appliances must support such interfaces.
n
Do not create the GRE tunnel over LAN.
