Hi All, Thanks for your feedback on the L3 (forwarding) proposal during the summit and also prior to that. The action item coming out of the summit session was to further discuss this with the Melange/IPAM team to identify points of overlap and/or what are the additional requirements. Accordingly, after focused discussions with many folks including Troy, Jason, and Trey from the Melange team, it seems that we are pretty much on the same page in terms of what the L3 (forwarding) proposal wants to achieve and how IPAM will support the data-store aspects of this.
There are constructs like the ip_block in (former) Melange which map to the Subnet (in the L3 forwarding proposal). There are others like the route-table and targets which might not have a direct mapping, and which might need to be realized separately. These in turn might drive further requirements on the IPAM component, but this will be clearer once we start implementing the L3 forwarding proposal. Also, realizing the target abstraction will need plugin-level support which might differ based on the type of the target being realized and the underlying network infrastructure. So the plan is to go forward with the implementation of both IPAM and L3 route-table/target API, with both going into the trunk branch. The work on L3 will hopefully drive any further needs on the IPAM component. Specifically on the ip_block/subnet construct, the current thought is to call it a Subnet. Also, this is better modeled as a separate construct, rather than an attribute in the virtual network resource, since we should be able to model 1:n and n:1 relationships between L3 and L2 networks. Please let us know if you have any further thoughts on this.
