[Nsi-wg] Topology virtualisation

[Gigi Karmous-Edwards]

Ok, sorry, I meant to say.... I assume that if a GOLE is policy free, 
then the connection between a
domain and a GOLE is really based on the policy of the domain that the 
GOLE is connecting to.

Victor, are you saying that the link between two GOLEs will be 
represented as a autonomous domain? If so, what NSA (NRM) would 
advertise this small-single-link domain? Whose policy would be advertised?

How does this work today with links between Starlight and NetherLight, 
or ManLAN and StarLight?
