# linux bridges on compute node

I am trying to trace a packet from the source to the destination on a havana environment. Ping between the compute VMs created on two different compute hosts is successful, but I am not able to ping the instances from the network node which has an interface on the same physical L2. I see the packets go up to int-br-eth1, but then it does not make it to the tap device via br-int.

The neutron guide indicates that the tap devices of the VMs connect to a linux bridge (qbr) which then uses a veth pair (qvo and qvb) to connect to the integration bride (br-int). However, when i run ovs-ofctl against br-int, I actually see the veth pair from the physical device's bridge (phy-br-eth1) and all the tap devices themselves. Is there something that I am missing here? Any pointers would be very helpful.
