<div>Hi Yong,</div>
<div> </div>
<div>I downloaded the Quantum Architecture in Folsom Powerpoint
prepared by you and found that in slide-10:</div>
<div><span
style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt"> </span><br>

<div
style="TEXT-ALIGN:left;LINE-HEIGHT:93%;MARGIN-TOP:12.13pt;DIRECTION:ltr;MARGIN-BOTTOM:0pt;VERTICAL-ALIGN:baseline"><span

<div

style="FONT-FAMILY:Wingdings;COLOR:black;FONT-SIZE:45%">l</span></span><span
style="">To implement floating </span><span style="">Ips</span><span
style=""> and other L3 features, such as NAT</span></div>
<div
style="TEXT-ALIGN:left;LINE-HEIGHT:93%;MARGIN-TOP:1pt;DIRECTION:ltr;MARGIN-BOTTOM:0pt;MARGIN-LEFT:0.56in;VERTICAL-ALIGN:baseline"
class="O1"><u><span style="FONT-SIZE:14pt"><span
style="FONT-FAMILY:Wingdings;COLOR:black;FONT-SIZE:45%">l</span></span><span
style="">One per network</span></u></div>
<div> </div>
<div> </div>
<div>Can you elaborate on the comment 'one per network' for
L3-Agent.</div>
<div> </div>
</div>
</blockquote>
# If use_namespaces is set as False then the agent can only
configure one router.<br>
# This is done by setting the specific router_id.<br>
# router_id =<br>
<br>
# Each L3 agent can be associated with at most one external
network. This<br>
# value should be set to the UUID of that external network. If
empty,<br>
# the agent will enforce that only a single external networks exists
and<br>
# use that external network id<br>
# gateway_external_network_id =<br>
<br>
two options:<br>
1. use namespace = False and set router_id to specific one can
support multi l3-agent,<br>
or<br>
2. create multiples external networks, and use
gateway_external_network_id = to run multil3-agent<br>
This way, we must set router's gateway port:<br>
we can create router with external_gateway_info:<br>
such as quantum router-create router1 --external_gateway_info
network_id=<id><br>
or quantum router-create router2<br>
quantum router-gateway-set<br>

<div dir="ltr">
<div>As i understood that the L3-Agent will be only one for
complete setup.</div>
<div>If we have more than one Network Node then we must install
dhcp-agent and L3-Agent in each of these Network Nodes.</div>
<div> </div>
<div>So, the comment of 'one per network' is like we can have
one router/gateway per tenant network.</div>
<div> </div>
<div>Can you give us your comments on this.</div>
<div> </div>
</div>
</blockquote>
you can reach at this target by creating a router or external
network per tenant.<br>

<div>Hi Yong,</div>
<div> </div>
<div>Thanks for information.<br>
</div>
<div>I think you mean to say that these Quantum Network Node
is not per Tenant basis and it can serve all the Tenants
of DC setup.</div>
<div> </div>
<div>Just want to understand what will be the advantages we
are thinking of by doing so.</div>

<div>Hi,<br>
In fact, we can split Quantum network Node into two
categories:<br>
one is for dhcp, which install ovs agent and dhcp
agent. We can have one such kind of node<br>
one is for l3 agent, we can deal with one external
network on one l3 agent. We can have many nodes of
this kind.<br>
<br>

<div>Hi Salvatore,</div>
<div> </div>
<div>Just want to understand more on Network
Node in the below given app_demo page.</div>
<div> </div>
<div>As i see in the setup, it looks like there
will be one Quantum Network Node for one Data
centre setup. Please correct me if my
assumptions are wrong.</div>
<div> </div>
<div>This Quantum Network Node will have all the
virtual routers, gateway which can be created
with quantum-l3-agent plugin.</div>
<div> </div>
<div>Also my assumption is that this quantum
Network Node will serve all the Tenant
virtual gateways and routers created using
quantum.</div>
<div> </div>
<div>Please give us some more information on
this to understand the setup.</div>
<div> </div>
<div>Also do we have any specific reason for
having quantum Network Node instead of keeping
these plugin on the Controller Node similar to
earlier release like Essex.</div>
<div> </div>
<div>Thanks in advance.</div>

Trinath,

</div>
<div>Even if is perfectly reasonable to run
the DHCP/L3 agents in the controller node,
the advice we give in the administration
guide is slightly different.</div>
<div>As suggested in [1], the only Quantum
component running on the controller node
should be the API server.</div>
<div>The DHCP and L3 agents might run in a
dedicated "network node". Please note you
will need also the L2 agent running on
that node.</div>

<div>Hi Stackers-
<div><br>
</div>
<div>I have found many
installation and configuration
manuals for Openstack Folsom
which state the installation and
configuration of
Quantum-DHCP-Agent in the
Controller machine.</div>
<div><br>
</div>
<div>But I have doubt here, </div>
<div><br>
</div>
<div>Can't we have the
Quantum-DHCP/L3-Agent to be
running in the Compute NODE
rather than in the controller.</div>
<div><br>
</div>
<div>How does the Installation and
configuration change with this
type of Installation?</div>
<div><br>
</div>
<div>Please guide me on How to
achieve the same.</div>
<div><br>
</div>
<div>Thanking you <span><font
