Maybe I'm wrong, but I thought that the extended MPLS info only showed up when the trace was started on a PE or P router. Is that right?
I did the traceroute from a router with _NO_ mpls commands turned on, and it's on a network that uses _NO_ mpls today. Basically from reading the draft if the router that generates the ICMP unreachable received the packet with an MPLS label, it adds the MPLS info to the returned data. As long as your traceroute can parse/show it (so far I've only confirmed Juniper can do it), it will be displayed to the world. -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request () tmbg org, www.tmbg.org
