Hi
   Given that there are OVS1 and OVS2, two VXLAN between these, 
VXLAN1000 and VXLAN2000 belong to same Bridge.
OVS1 send a packet through VXLAN1000, then VXLAN2000 of OVS2 will forward it 
once VXLAN1000 receive the packet.
So OVS1 will also receive the packet, next VXLAN1000 of OVS1 send it again.
The packet will continuously send between OVSs.
 
OVS1:
Bridge br2        
  Port "vxlan2000"              
   Interface "vxlan2000"                 
   type: vxlan                 
        options: {key="2000", remote_ip="2.2.2.1"}       
  Port "vxlan1000"             
   Interface "vxlan1000"                 
   type: vxlan                 
            options: {key="1000", remote_ip="1.1.1.1"}         
  Port br2             
   Interface br2                
   type: internal
 
OVS2:
Bridge br2        
  Port "vxlan2000"              
   Interface "vxlan2000"                 
   type: vxlan                 
        options: {key="2000", remote_ip="2.2.2.2"}       
  Port "vxlan1000"             
   Interface "vxlan1000"                 
   type: vxlan                 
            options: {key="1000", remote_ip="1.1.1.2"}         
  Port br2             
   Interface br2                
   type: internal

These are just ports that will receive a given VNI.  Once the packet
is received, the ports are bridged together.
