Q RE N-POPS Value in LSR MIB

Hi,
    Sorry if this has been answered already.

    I'm a little confused as to how the N-POP value in the LSR
    MIB is used in practice.

    i.e. if the N-POPS is > 1, say 2, which of the following is the
    correct behaviour assuming an incoming label stack size of 3.

    1] Pop 2 labels and lookup and forward according to the remaining
         label.

    2] Perform a lookup using each label before it is "popped", if this
        is the case i'm not sure what use the N-POP value is as the
action
        is specified by the lookup result in each case.

        thanks in advance
Paul
