I am given an built Openstack environment to support. The environment is Redhat Openstack Liberty release. It is integrated with Cisco ACI as part of network design. Controller and Compute node is connected to a network for Opflex communication. Right now I see VM's which are already launched and floating IP associated with it. When I look into the compute node,I could see only tap interface associated with the port. No ovs bridges. No Linux Bridge.

I would like to understand how do the traffic flow to be traced from VM to external network ? If you need any additional details, please let me know.

ACI network design is kind of not publicly documented. I would request support to Cisco for that. For what I can remember from an old environment. Compute nodes are connected to ACI through an interface, then the network is routed to outside in ACI. (No bridged/ovs because ACI does not use them)
