What is causing a significant amount of the message (A segment before this frame was lost) in traffic on a MPLS routed WAN. Any help is appreciated. Running IBGP on MPLS backplane. Errors only noticeable on DS3 pportion of circuit. The following is DS3 output interface info from the router:

I think you got this type of error :
"The segment before this frame was lost" Look for one of these frames in "Frame 78". Can you send me the sniff trace of that site in particular which you had problem with over the tunnel.
The following url will help you
