[ovs-discuss] packet leaking across vswitches

Dear all,

see weird things only with openvswitch, even the latest version, that potentially packet will leak from one vswitch to another, even those two vswitches are configured  separately with different physical NICs on different VLAN trunks. No patch/tunnel ports involved. We see looping detection happens to these two uplink ports.


      - eth0

      - port with vlan 100


      - eth1

      - port with vlan 200

Can someone explain if this is possible the packet from vlan 200 on vswitch1 can reach vswitch2?

Thanks & Regards
