Hi Diego,

Stewart,
I think i agree here.
Even if i'm coming from sdh i don'e see the need to hane osi capability
in brand new mpls-tp boxes.
I actually do not fully agree here. If, due to historical reasons, the
existing DCNis an OSI network and if the new MPLS-TP boxes will only understand IP and have
to use the existing OSI-based DCN, then the new MPLS-TP boxes need to support
at least tunneling of IP over CLNP tunnels. Otherwise, a dual stack DCN would
indeed be needed (I am assuming here that the existing OSI-only DCN cannot be
turned into an IP-only DCN).
Cheers,
Dieter
