I think this is a cool idea, but I'd submit that we may want to make some additional considerations if we're talking about adding routing protocol support to the VRs.
One thing we're doing here at ENA right now (outside of Cloudstack VRs) is running BGP on VMs in order to manage floating ips (anycast BGP). If the effort is going to go in to run OSPF up to a P/PE router, it makes sense to also support BGP on the public interfaces. This opens up a lot of exciting possibilities in terms of being able to provide native support for intelligent geographic based services (i.e. GSLB without DNS). Just my 2 cents. - Si ________________________________ From: Abhinandan Prateek <abhinandan.prat...@shapeblue.com> Sent: Tuesday, January 5, 2016 9:20 PM To: dev@cloudstack.apache.org Subject: Re: [PROPOSE] Dynamic inter VPC routing [ShapeBlue]<http://www.shapeblue.com> Abhinandan Prateek Software Architect , ShapeBlue d: | s: +44 203 603 0540<tel:|%20s:%20+44%20203%20603%200540> | m: +91 970 11 99011<tel:+91%20970%2011%2099011> e: abhinandan.prat...@shapeblue.com | t: <mailto:abhinandan.prat...@shapeblue.com%20|%20t:> | w: www.shapeblue.com<http://www.shapeblue.com> a: 53 Chandos Place, Covent Garden London WC2N 4HS UK [cid:image556e34.png@8ef18889.4f85c6ff] Shape Blue Ltd is a company incorporated in England & Wales.

There are several options here: 1. Hardcoded, user does not worry about CIDR selection. 2. Have him pick up the mask, cloudstack allocates the CIDRs. Yes, the document initially assumed a rigid system of allocation of CIDRs, but after internal discussion it was decided that we allow user to pick up the masks. It seems you are also pointing in that direction. Will update the doc soon. -abhi > Find out more about ShapeBlue and our range of CloudStack related services: IaaS Cloud Design & Build<http://shapeblue.com/iaas-cloud-design-and-build//> | CSForge - rapid IaaS deployment framework<http://shapeblue.com/csforge/> CloudStack Consulting<http://shapeblue.com/cloudstack-consultancy/> | CloudStack Software Engineering<http://shapeblue.com/cloudstack-software-engineering/> CloudStack Infrastructure Support<http://shapeblue.com/cloudstack-infrastructure-support/> | CloudStack Bootcamp Training Courses<http://shapeblue.com/cloudstack-training/>
