Hello, I am a little confuse after read snippet instruction. I want first to have a brief of my environment. I have two machines, each of them has 2+ nics. I want to use 2 of them both. One is for controller (api+network), another is for compute node only (compute-nova). but the two of nics will use same subnet IP (such as 10.0.0.11 eth0, 10.0.0.2 eth1). My original idea is to act eth0 as management network/storage/api/tenant, eth1 is for external network. my operating system is centos7, and rdo juno. any suggestion how to design my network? which network type should i choose? gre/vxlan? If you have advise any exist article for me to reference, it should be better. Thanks, Eugene

Vew RDO Juno Set up Two Real Node (Controller+Compute) Gluster 3.5.2 Cluster ML2&OVS&VXLAN on CentOS 7 .
Link posted exactly match your needs , details related with Gluster Cluster set up may be just skipped as well as LVMiSCSI backend set up for Cinder. VXLAN tenant's tunnels (RDO Juno) connecting Compute Nodes to Network Node is a standard approach. You would have update answer file provided, because it's using eth0 for public&&management network, eth1 for endpoints of VXLAN tunnel. Placing management network and VXLAN endpoints on the same interfaces might cause network congestion , so I would recommend plug third Ethernet NIC into Controller+Network Node for public network support

Answer file provided works on CentOS 7 and F21 . It was used in my lab for mult inode deployment RDO Juno Controller+Network+2xCompute nodes after some updates. I wouldn't advise you use same NICs for mgmt network and VTEPs
