Hello all,

Thank you, Marco.

I would like to build on those two clarifications.

To provide a concrete example, we can consider a single data-centre
facility operated by one infrastructure provider.

Each tenant/subscriber has a direct contractual relationship with the
provider, and each environment has one stable /48. Although they share the
same physical premises, the networks are separately connected and
administered.

One of those tenants also operates twelve persistent virtual network
environments inside its tenant environment. The infrastructure provider
makes the assignments directly. The environments fall into exactly three
groups:

   - Some have their own ASN and independent routing policy.
   - Some share common routing domain but have their own management domain
   and independent operational lifecycle.
   - Some share the routing and management systems but are isolated by a
   strict security boundary with no lateral connectivity.

This is intended as a concrete case where the physical site, the
operational site and the routing site do not coincide. Each environment is
stable and retains the same /48.

Depending on the test applied, the relevant End Site could be:

   - The whole physical facility;
   - Each tenant;
   - Only the environments with independent routing;
   - Or each operationally or securely separated environment

Possible directions for clarification might therefore include defining the
End Site by the subscriber relationship, physical premises, routing
boundary, operational domain, or an explicit combination of those factors.



I would be interested in how others would classify the three groups above
and which underlying test they would apply.

Best Regards,

Yuli
