I am trying to install a Havana implementation on the centos nodes (separate controller, compute and network node). I have the following nics Controller has 3 nics: 1) Nic 1 is connected to 135.227.248.250 (external network) 2) Nic 2 is connected to switch1 (assigned Ip 192.168.0.10 )

Compute has 3 Nics 1) Nic 1 is connected to 135.227.248.240 (external network) 2) Nic 2 is connected to switch1 (assigned Ip 192.168.0.11 ip) 3) Nic 3 is connected to switch 2 (assigned Ip 1.1.1.1)

Network has 3 Nice 1) Nic 1 is connected to 135.227.248.204 (external network) 2) Nic 2 is connected to switch1 (assigned Ip 192.168.0.12 ip) 3) Nic 3 is connected to switch 2 (assigned Ip 1.1.1.2)

Can someone explain me what each networks are used for? I am assuming the vm data network is on switch 2. Can someone explain me how the br-int and br-ext work on the compute and network node? Any explanation is helpful

Thanks

In short, Management network is for communication between components of openstack; data network is to communicate between VMs; external network to connect to/from outside. Concerning br-in and br-ex, look here
