RE: Layer 2 Switching Caps LSPs

["Mack-Crane, T. Benjamin" <Ben.Mack-Crane@tellabs.com>]

Dimitri,

As I think Sharam has noted, 1) is a physical interface.  How packets
are transferred from one interface to another is the question.  2)
defines behavior for this (and 3) is just one feature of this behavior).
If you are not referring to 2), what defines the forwarding behavior?
Just saying all received packets are sent is not adequate (at least this
was not deemed adequate by earlier efforts to define Ethernet P-P
service).


Regards,
Ben
