[j-nsp] M7i and M10i problems - TRACE ROUTE

[Giuliano Cardozo Medalha]

People,

We have a Juniper M10i border router.

When we install this router on our network ... we are having problems 
with MTR and traceroute programs.

Basically ... every trace that pass trough the router lose 70% of the 
packets.

PING just works fine ... but TRACE and MTR not.

Juniper saids in J-TAC that this is a default config (FACTORY DEFAULT) 
from the router.

There is some command or way to change this behavior ?

Thanks a lot,

Giuliano
