<div class="moz-cite-prefix">Hi Anil,<br>
<br>
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.<br>
<br>
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).<br>
<br>
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)<br>
<br>
Is it clearer ?<br>

<div>Hi All,</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>OS Network Administrator Guide says "<span
style="font-size:13.333333969116211px;font-family:Verdana,Geneva,sans-serif">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. </span></div>
<div><span
style="font-size:13.333333969116211px;font-family:Verdana,Geneva,sans-serif"><br>
</span></div>
<div><span
style="font-size:13.333333969116211px;font-family:Verdana,Geneva,sans-serif">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? </span></div>
<div><span
style="font-size:13.333333969116211px;font-family:Verdana,Geneva,sans-serif"><br>
</span></div>
<div><span
style="font-size:13.333333969116211px;font-family:Verdana,Geneva,sans-serif">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.</span></div>
