This must have been resolved by the latest security uploads that
contains the latest upstream release for the 2.10 branch.

Puppet is what my installer (link above) uses. :)

With my cluster management software, you can do either a big L2 segment,
or using routing to the host (BGP networking). However, in the later
case, you must not use DVR (so all of the trafic goes through the
network nodes, which must be L2 connected).
We're very happy with bgp-to-the-host, it scales very well, and it's
easier to manage than EVPN on the switches.
