I agree 100% with your statement below!
Longer than a /48. That would eliminate any
concerns I have. /48's could be assigned to each POP
giving basic location information for any downstream.
That is similar to BCP of a /24 for IPv4. If a downstream
business request SWIP that we can accommodate.

Take care
Paul
