Hi Jaume, The concept of provider router is useful as it maps what actually already happens in several infrastructures. I am not entirely sure that this however implies we need to expose new API constructs and change the topology API.
The provider router perhaps can exist in a concealed way, where tenants still put gateways on an external network, but that would be implemented with a provider router. Anyway, I am sure you are aware of the technical debt repayment activities scheduled for Kilo. Some of them pertain the l3 agent , and I'd say those have the highest priority. If this spec will bring non-negligible changes in the l3 agent, perhaps it's the case of doing that after the agent restructuring to avoid conflicts which will slow down everything. Finally, can you post the specification for this work in gerrit? It seems it is not the one under the 'edge router' name  Salvatore  https://review.openstack.org/#/c/131535/  https://review.openstack.org/128272 On 31 October 2014 10:01, Jaume Devesa <devv...@gmail.com> wrote: > Hi all, > > in Midokura we are working on a blueprint to define a new kind of topology > for floating ranges, as alternative to external network topology.
