[c-nsp] Carrier Supporting Carrier

[McCallum, Robert]

With CSC you run LDP between the two devices.  With Inter-AS vpns you run
EBGP (i think).  Multicasting over both scenrios is completely different as
well.

Yes,Robert but would that not also be CsC because when the ISP in US
provides
only a backbone (no MPLS service ) to the Tier 3 ISP in Asia Pac who is
connected
to another ISP with another AS # in US (these two have IP and MPLS VPNs)
over the
bigger ISP.
 
This is how i have understood it because the Deisgn option 2 and 3 of Inter
AS VPNs
per cisco are very close to the CsC design config. If i have wrongly
undertsood can u
please add how would one see CsC.
 
Thanks

Annu.
