I don't know of any products that currently use the L3 features of vtep. I
know hardware vendors are just starting to support it, and I suspect
controllers will start to add support soon.
For OVN, we support L2 through the vtep schema. We plan to add L3 support for
vtep eventually, but our focus at the moment is to implement a pure software
gateway that supports L2, L3, NAT, etc. If someone wants to work on OVN's vtep
L3 support, we'd gladly accept patches, but I'm not aware of anyone working on
it currently.

The current documentation is in the master OVS repo. There's a slight outdated
version here, though:

As I mentioned, I don't know anyone that is currently working on L3 vtep
support for OVN. However, when that support is eventually added, I wouldn't
expect it to require northbound changes.
