Question

My question to you is, do I need to configure eth1 on the Compute Node as a bridge similar to br-ex on the Controller Node? Do I even need the Compute Node to be connected to the Public Network or can it pass the networking traffic over the Management Network?


In general answer is NO, unless you deploy DVR with bridged networking.

However, your design is missing third network connecting Compute and Controller. It might be VXLAN or GRE tunnel either VLAN tagged vm/data network. This third network is responsible for routing SOUTH-NORTH && EAST-WEST traffic via Controller/Network Node, unless DVR has been setup

MGMT network might be used as VXLAN tunnel , what could cause network congestion and is not recommended for production deployments.
