Hi Yong,
I downloaded the Quantum Architecture in Folsom Powerpoint prepared by
you and found that in slide-10:
lL3-agent
lTo implement floating Ipsand other L3 features, such as NAT
_lOne per network_
Can you elaborate on the comment 'one per network' for L3-Agent.
# If use_namespaces is set as False then the agent can only configure
one router.
# This is done by setting the specific router_id.
# router_id =
# Each L3 agent can be associated with at most one external network. This
# value should be set to the UUID of that external network. If empty,
# the agent will enforce that only a single external networks exists and
# use that external network id
# gateway_external_network_id =
two options:
1. use namespace = False and set router_id to specific one can support
multi l3-agent,
or
2. create multiples external networks, and use
gateway_external_network_id = to run multil3-agent
This way, we must set router's gateway port:
we can create router with external_gateway_info:
such as quantum router-create router1 --external_gateway_info
network_id=<id>
or quantum router-create router2
quantum router-gateway-set
As i understood that the L3-Agent will be only one for complete setup.
If we have more than one Network Node then we must install dhcp-agent
and L3-Agent in each of these Network Nodes.
So, the comment of 'one per network' is like we can have one
router/gateway per tenant network.
Can you give us your comments on this.
you can reach at this target by creating a router or external network
per tenant.
bye,
balaji

Hi Yong,
Thanks for information.
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.
Just want to understand what will be the advantages we are
thinking of by doing so.

Balaji

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

Hi Salvatore,
Just want to understand more on Network Node in the below
given app_demo page.
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.
This Quantum Network Node will have all the virtual routers,
gateway which can be created with quantum-l3-agent plugin.
Also my assumption is that this quantum Network Node will
serve all the Tenant virtual gateways and routers created
using quantum.
Please give us some more information on this to understand
the setup.
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.
Thanks in advance.
Regards,
Balaji

Hi Trinath,
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.
As suggested in [1], the only Quantum component running
on the controller node should be the API server.
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.

Salvatore

Hi Stackers-
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.
But I have doubt here,
Can't we have the Quantum-DHCP/L3-Agent to be running
in the Compute NODE rather than in the controller.
How does the Installation and configuration change
with this type of Installation?
Please guide me on How to achieve the same.
Thanking you
