GRE is a standardized protocol so there aren't really "advanced features"
per se. However, the Open vSwitch implementation supports a large number
tunnels and has significantly higher performance when compared to other
GRE is just tunneling Ethernet frames between switches so a broadcast packet
will be broadcast by a remote switch, regardless of where it is.
