Hello, I have 3 bare-metal servers therefore, I went for 2+2 aio-duplex setup. Simple non-manageable switch. (No vlans) controller-0 - 3 NIC, 1 for mngmt/cluster, 1 for OAM, 1 for data network. controller-1 - 3 NIC, 1 for mngmt/cluster, 1 for OAM, 1 for data network. worker-0 - 2 NIC, 1 for mngmt/cluster, 1 for data network. Thus, I am wondering what would be the right process of adding data network to openstack setup? What I ve already tried: 1. Added flat data network on each node: system datanetwork-add physnet0 flat 2. Created external network in openstack: ENABLE_EXT_NET=${ENABLE_EXT_NET:-1} EXT_NET_CIDR=${EXT_NET_CIDR:-'10.0.2.0/24'} EXT_NET_RANGE=${EXT_NET_RANGE:-'start=10.0.2.150,end=10.0.2.199'} EXT_NET_GATEWAY=${EXT_NET_GATEWAY:-'10.0.2.1'} openstack network create --external --provider-physical-network physnet0 \ --provider-network-type flat public1 openstack subnet create --no-dhcp \ --allocation-pool ${EXT_NET_RANGE} --network public1 \ --subnet-range ${EXT_NET_CIDR} --gateway ${EXT_NET_GATEWAY} public1-subnet openstack router set --external-gateway public1 demo-router Using this setup, I cant have any virtual network in openstack using vxlan? If I have dhcp enabled for public1 network, I can create vm assigned with public1 network and ping/ssh machine directly. However, what I can do if I want to have private network and use public1 for my floating ip's? Do I need to have 1 more NIC card and assign data-network(vxlan) to that? Thank you
