Also, note that the Modular L2 (ML2) plugin does not hard-wire a particular implementation of the L3 router API. There is a service plugin that implements this via Neutron's l3-agent, but other options are possible as well (and are being developed).

You are also free to not use the L3 agent at all and just patch a few virtual 
routers into the L2 segments you want them to route (obviously this will result 
in floating IPs, routing, etc not being managed by Neutron).

I think you are looking for multiple neutron-l3-agent. It is possible and has 
been discussed many times before in mailing lists. Just do a google search 
'multiple l3 agent in openstack' you should be able to find some link to start 
with.

Subject: [Openstack] Network Architecture - Separate Layer 2 and Layer 3 - 
neutron/network node only l2

Hello,


I'm writing to you because I'd like to discute about the separation of layer 2 
and layer 3.

Can openstack network node only work on layer 2 with a dedicated server ? and 
all layer 3 configuration done elsewere ?

The idea is :  netowk node manage layer 2 topologie (openvswitch/gre tunnel) 
and  Layer 3  is dedicacted to virtual machine/application.
For evry tenant i'm thinking about a VM doing all L3 jobs (router, firewall, 
loadbalancing, ....)

Did you see what i mean ? Is it possible ?

Thank you in advance !

Regads,

ps : sorry for my english ;)
