[j-nsp] MPLS labels on a traceroute across an IXP?

[Gavin Henry]

Hi all,

Please excuse my ignorance, but having just got into junos I've
noticed on a traceroute today this:

traceroute to xx.xx.xx.xx (xx.xx.xx.xx), 30 hops max, 40 byte packets
 1  xx.xx.xx.xx (xx.xx.xx.xx)  2.504 ms  5.024 ms  2.937 ms
 2  xx.xx.xx.xx (xx.xx.xx.xx)  15.254 ms  15.300 ms  15.887 ms
 3  lonap-gw2.plus.net (193.203.5.155)  15.076 ms  15.103 ms  16.043 ms
 4  te-9-1.ptw-gw02.plus.net (212.159.1.19)  15.844 ms  16.082 ms  15.642 ms
     MPLS Label=9814 CoS=0 TTL=1 S=1
 5  link6-central10.ptw-ag01.plus.net (84.93.248.11)  20.964 ms
32.774 ms  55.808 ms
 6  * * *
 7  * * *
 8  * * *


Now I've never seen:

MPLS Label=9814 CoS=0 TTL=1 S=1

on a traceroute before (being new to MPLS too :-) ) and presume it's
showing because of the junos traceroute, whereas I don't see it from
the same
network on a linux box?

My other question is should this actually show and not be remove by
the egress LER?

Thanks,

Gavin.
