Hi Guys,

I'm looking at some way to debug mpls traffic. 

We have equipments with MPLS network as following. 

A ---  MPLS PE node(PE-A)  --------------- MPLS PE node (PE-B)  ---  B


>From A ethernet segment, and B ethernet segment, we installed ethernet 
capturing machine, and found A sent SIP message 183 to B.
But it seems like B never receive SIP message 183 from MPLS PE node PE-B. 
So it seems SIP message 183 is disappeared from the MPLS network.
Funny thing is other messages or packets looks fine, and when I tested 
ping from this MPLS vrf domain, it is fine. 

Is there any way for JUNOS to trace (debug)  specific MPLS message for 
troubleshooting?
