<div>Hi,</div>
<div> </div>
<div>Iam having essex setup [where we dont have Quantum Network] and now if we want to have Folsom setup and if we dont want to use L3-Agent and Quantum router for DNAT of Floating-IPs.</div>
<div> </div>
<div>How can we achieve this with Folsom.?</div>
<div> </div>
<div>As well i want to understand the real time deployment of Teanant VMs for Public Access using Public -IPs, I hope it can be achieved in Folsom setup as well. Can any one give me inputs on this.</div>
<div> </div>
<div>Just curious to understand the quantum router use case apart from NAT,iptable rules any other advantages we have in real time deployments.</div>
<div> </div>
<div>please share your understanding and experience.</div>
<div> </div>
<div>Thanks in advance.</div>
<div> </div>
<div>regards,</div>

<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> </div>
<div> </div>
<div>Can you elaborate on the comment 'one per network' for L3-Agent.</div>
<div> </div></div></blockquote></div># 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
<div class="im"><br><br>
<blockquote type="cite">
<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></div>you can reach at this target by creating a router or external network per tenant.

<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>

<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>

<div><br></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>
