Re: VCn-xV LSPs terminology
Hi Wataru, Dieter,
yes I agree with both of you.

I understand your question is whether we shoud call LSP on
the basis of signaling session or not.
If so, IMHO is Yes.
The VC4-7v with single RSVP session is single LSP.
On the other hand, VC4-3v + VC4-4v with two RSVP session is two LSPs.
However, both of them are single LSP in the client layer as Dieter said,
That is my understanding.
But is that right, all ?
