Shane, Interesting. I’m trying to imagine the topography because CB2 does have the concept of a network with multiple IP ranges assigned. Can you give a concrete example w/ IP subnet and function that you’d split?
I’m not sure how you’d pick which range was tied to a L2 boundary for assignment. Would IPv6 help solve this?

All, I have a question regarding Crowbar deployment. Currently - I have deployed Crowbar 1.x in a flat L2 physical topology. Meaning - all of the OpenStack cluster members are in a single L2 domain. We are working on a physical datacenter topology where every single rack is an L2 boundary. Inter-rack traffic (east/west) is an L3 boundary. We will be utilizing OSPF and BGP to provide inter-rack redundancy and HA capabilities (I.e. no spanning tree between racks for failure). My question - can Crowbar network barclamp support multiple L3 network segments for a single cluster deployment? I don’t recall any documentation or designs that point to this being a capability (in 1.x). If that’s the case - does OpenCrowbar 2.x incorporate the capability in the design to support deploying a cluster across different L3 networks in a single cluster? Thank you, ~~shane
