Hi Anil,
What you quoted is about L3 management and bridging and the need of
flexibility. It means that the physical NIC will have a whole bunch of
IP addresses, one per Quantum router you define.
Should you want to deploy a Controler on that node, you would need to
have a second NIC with external access (what is called "API Network" in
the docpage Simon quoted).
There is also need for "Data Network" with ideally a third NIC (if you
want to provide separate IP ranges for API and data network) but you can
bypass that in a lab environment by assumpting that your data network IP
range is externally reachable and consequently the management IP of the
controler/network node is the public IP (for the API purpose) (here,
NIC2 IP address)
Is it clearer ?

Subject: [Openstack][Quantum] Query regarding floating IP configuration
To: "openstack@lists.launchpad.net
<mailto:openstack@lists.launchpad.net>" <openstack@lists.launchpad.net

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.
