*I have vm connected to linux bridge which is then connected to ovs bridge
using veth pairs *qvocb9f0e52-99(ovs end) and qvbcb9f0e52-99 (native bridge
end)
*
*
qvocb9f0e52-99 is then connected to br-int .*
*
br-int has one of the veth pair connected ie int-br-eth0 and other end
phy-br-eth0 to br-eth0 on which physical nic eth0 is connected.
When i make ping request from vm, through tcpdump i can see ARP Request
reaching till phy-br-eth0,but not on br-eth0 on which eth0 is bridged.
What could be the reason for ARP request not reaching bridge but reached
one of its port.There is no custom flows nor controller.

Any idea why ARP request can not reach br-eth0
