Open Stack

Hi everyone,

Sorry, I couldn't make it in time for the IRC meeting.

Just saw in the logs:
15:19:12 <yamamoto> are orange folks here?  they might want to
                     introduce their bgp speaker.

The best intro to BaGPipe BGP is the README on github:
https://github.com/Orange-OpenSource/bagpipe-bgp/blob/master/README.md

Beyond just speaking the BGP protocol on the wire, BaGPipe is a an 
implementation of BGP VPNs (IP VPNs and E-VPNs) including the forwarding 
part. It can be run as a service exposing a REST API, or a library 
inside an agent; it handles the lifecylcle of VRFs and port 
attached/detached from them and appropriately circulates event to/from 
BGP peers based on VRF import/export rules and RTC publish/subscribe 
semantics.  It's complete enough to let us build neutron virtual 
networks with IP VPNs, and interconnect them with external VPNs; the 
parts for Opentsack integration are not on this github, I'm just 
mentioning this for the sake of illustrating the relative maturity.

Although it does not address plain IP, this would I believe by a really 
easy addition to make.

I'll do my best to attend next week IRC meeting, but until this, feel 
free to ask.  We can also do a Q&A session on IRC if that sounds convenient.

Best,

-Thomas
