Thank you,but could you give me an example about gre
my configuration
Bridge "br0"
Port "br0"
Interface "br0"
type: internal
Port "tap1"
Interface "tap1"
Port "eth0"
Interface "eth0"
Port "gre0"
Interface "gre0"
type: gre
options: {remote_ip="192.168.0.156"}
ovs_version: "1.7.1"
do you mean drop the packets from eth0 to gre0?
