Hi Sumit and Networking folks This is continuing discussion of this week openstack networking project. Multiple service is going to inject new function for Logical Router, however we are lacking framework for injecting functions for l3-agent so I wrote some options in this slide. https://docs.google.com/presentation/d/1e85n2IE38XoYwlsqNvqhKFLox6O01SbguZXq7SnSSGo/edit#slide=id.p I prefer Option2-1 for now, and migrate for option2-2 later in the slide. Thanks Nachi
