Hi,

The authors of the draft might like to clarify for the list exactly what
data plane operations they are suggesting. To me it seems possible that
the draft is proposing VLAN ID *swapping*. But an alternative is that the
VLAN ID is used as a label, but that the same label is used for the full
length of the LSP.

Adrian
