Hi All, I am trying to setup openstack in my lab, where i have a plan to run Controller+Network node on one physical machine and two compute node. Controller/Network physical machine has 2 NIc, one connected to externet network (internet) and second nic is on private network.
OS Network Administrator Guide says "The node running quantum-l3-agent should not have an IP address manually configured on the NIC connected to the external network. Rather, you must have a range of IP addresses from the external network that can be used by OpenStack Networking for routers that uplink to the external network.". So my confusion is, if i want to send any REST API call to my controller/network node from external network, i obviously need public IP address. But instruction i quoted says that we should not have manual IP address on the NIC. Does it mean we can't create floating IP pool in this kind of setup? Or we need 3 NIC, 1 for private network, 1 for floating ip pool creation and 1 for external access to the machine? OR is it that we can assign the public ip address to the br-ex, and remove it from physical NIC? Please let me know if my query is not clear. -- Thanks Anil
