[ovs-discuss] OVS VXLAN loop avoidance for 3 or more nodes

Hi,
I am testing a configuration with 3 ovs switches (representing 3 sites) and multiple vlan’s at each location. I am creating vxlan tunnels between each pair (total of 6 vxlan links). Each location has its own local DHCP server that assigns clients IP addresses for that site. However, what I’m seeing is that with the “NORMAL rules in the ovs bridge that has the vxlan connected, the DHCP traffic is sent thru and it seems to be creating a loop (when the mesh is 3 or more). Is there any way to prevent VTEP/VXLAN from either forwarding the DHCP traffic or alternately dropping that traffic on the other side.
Thanks in advance
DK
