Larry, See my comments below:
In an environment where the ToR is the NVE, then the NVA is attached to the NVE. How would you call this attachment? LK> I would expect anyone designing a ToR to make it capable of providing edge ports that are capable of being connected to either an overlay VN, or the the underlay. For example, if the ToR is a pure L2 device, I would expect some edge ports to be configurable to connect to a VN, and other port to connect to a VLAN which is connected to the underlay network. I would connect the NVA to the latter port. [Linda] The underlay network is L3 based. If ToR (NVE) is a pure L2 device, who advertises the NVA’s addresses to other NVEs? Under this environment, the NVE to which NVA is attached, has to be proxy for the NVA, i.e. announce the NVA address as if the NVA is embedded in the NVE. Bottom line, the NVE-NVA requirement should cover my suggestion being discussed over the emails. Linda
