<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I’m not sure I understand the relationship you’re drawing between BGP and L2 GW, could you elaborate? The BGP code that landed in Mitaka is mostly geared toward
the use case where you want to directly route your tenant networks without any NAT (ie no floating IP’s, no SNAT). Neutron peers with upstream routers and announces prefixes that tenants allocate dynamically. We have talked about how we could build on what
was merged in Mitaka to support L3 VPN in the future, but to my knowledge no concrete plan has emerged as of yet.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:black">In the M cycle BGP support was added in tree. I have seen specs in the L2 GW project for this support too. Are we planning to consolidate the efforts? Will the
BGP code be moved from the Neutron git to the L2-GW project? Will a new project be created?<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:black">Sorry, a little in the dark here and it would be nice if someone could please provide some clarity here. It would be a pity that there were competing efforts and
my take would be that the Neutron code would be the single source of truth (until we decide otherwise).<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri",sans-serif;color:black">I think that the L2-GW project would be a very good place for that service code to reside. It can also have MPLS etc. support. So it may be a natural fit.<o:p></o:p></span></p>
