[ovs-discuss] configure openvswitch in Amazon EC2

[俊 赵]

hi, all
i have installed openvswitch-2.3.2 in Amazon EC2, and want to use openvswitch to build a gre tunnel with other PC.
this is the ifconfig output








[root at ip-172-31-30-157 openvswitch]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 9001
        inet 172.31.30.157  netmask 255.255.240.0  broadcast 172.31.31.255

and route output

172.31.16.0     0.0.0.0         255.255.240.0   U     100    0        0 eth0

and i use the following commands
ovs-vsctl add-br OVS-SWITCH && ovs-vsctl add-port OVS-SWITCH eth0 && ifconfig eth0 0 && ifconfig OVS-SWITCH 172.31.30.157 netmask 255.255.240.0 && route add default gw 172.31.16.1 dev OVS-SWITCH
but after i execute these commands, i lose the connection with my ec2.
does anyone have deployed openvswitch in amazon ec2, and could you please give me some suggestions.
Many thanks!
