Hi Giuliano, Is this a MPLS-VPN environment?
I think you may be looking for the functionality from RFC4379. If that is the case, have a look at Junos 8.1: http://www.juniper.net/techpubs/software/junos/junos81/rn-sw-81/rn-new-features.html on the "MPLS LSP traceroute supported on transit router" section. regards, Paulo Estante JNCIE #185 On 4/22/07, Alex <[EMAIL PROTECTED]> wrote: > Giuliano, > AFAIK, the answer is no.
