Hi All,

A few questions regarding LSR-MIB: 

1) If TTL expires in an MPLS packet is the packet
counted in 
mplsInSegmentErrors" or not?

2) If we receive a labeled packet and swap the label
and then push a new label
do we keep 2 sets of statistics on the outgoing
segment, one for the swapped
label and one for the pushed label or only one?

BTW, I also noticed that in LSR-MIB a swap consists of
a pop on incoming segment followed
by a push on outgoing segment, this is odd !! The
odder thing is that the incoming segment has
a parameter called InSegmentNpop in which "N"
identifies the number of pops to be performed on the 
insegment. How does one know in advance how many pops
to perform? If you know that, then it means
that all those labels that you pop are not used at
all.

Thanks,
-Shahram
