The determination is flawwed.   First of all, it's not mentioned in
the policy that
"networks that are capable of readily reallocating their existing
allocations across interconnected
network infrastructure with routing impact"    are to be considered
non-discrete.

If the applicant can determine that their networks are discrete based
on the criteria
for operating discrete networks, then their networks are discrete,
regardless of the
technical possibility of reallocating existing allocations.

Second,   just because it's technically feasible for "existing
allocations to be reallocated"
across interconnected network infrastructure,  does not mean it would
be appropriate
to do so.  There may be a performance or cost impact that causes this
to be extremely
problematic.     There may be a reliability impact with regards to the
operator's network
design, and survivability requirements,   there might be legal issues, etc.


Third....    there's really no such thing as a network that would not
be able to readily reallocate their existing allocations  with routing
impact.

"Build a tunnel"    (with routing impact), and any discrete network becomes
interconnected,  as long as both networks have indirect connectivity.
