GRE
GRE defines how to use one network protocol to encapsulate another
network protocol. The GRE protocol has two usages: Enterprise internal

requirement for the enterprise internal protocol encapsulation when
setting up the tunnel in China. The unique reason why the enterprise
adopts GRE is the encapsulation for the internal address.
