This is done by adopting the router_extra_attributes models. However, the NSX 'distributed' extension is slightly different in that it is visible to tenants and prevents router conversion (allow_put=false). PUT requests are made return the correct HTTP code; The access control misalignments will need to be adjusted via rules in policy.json. This will be properly documented.
