Hi Ihar,
Thanks for addressing the comments. I have a few more comments.
Please see below.
Since the VNI range for vxlan is now limited, I don't think any user can
use the ovn interconnect
feature of OVN. Can you please document it in the ovn-architecture.7.xml
(probably in the
OVN Deployments Interconnection section).

Can you please correct indentation for the above, It should be:
uint64_t vni = (is_ramp_switch
? datapath->tunnel_key
: datapath->tunnel_key | ((uint64_t) outport <<
12));

Since this option is a read-only option and CMS cannot configure it, can
you please move this
to another group ? Maybe a "readonly" group to document the options set by
ovn-northd ?
Please choose an appropriate name if "readonly" isn't fine.
Thanks
