Nobody said
after all that BGP is a mandatory part of any control plane in any
network
layer
I agree that there are optical or other L1 networks that have their
own control
plane. I just don't see why one would want to offer VPNs on top of these
without an intervening L3 network.

Acee,
I think we still have a "context" issue. In this contect the
"VPN" is itself a Layer 1 service, e.g., a SONET interface or a
lambda. There are no packet services in these networks, only an IP
control plane controlling circuits.
Lou,
Understood - but are saying that there is no requirement to ever offer
these L1VPN
services in parallel with over L2/L3 services over a shared provider
network? If you can
truly limit the applicable to an environment where the control plane
only has the purpose
of L1VPNs then I wouldn't be that concerned (although I'd ask that the
IANA opaque
LSA ID allocation clearly state this - this WG chooses to go forward
with this approach).
Thanks,
Acee
Lou
