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 implementations. GRE is just tunneling Ethernet frames between switches so a broadcast packet will be broadcast by a remote switch, regardless of where it is.
