RE: Possible explanations for a large hop in latency

Interestingly enough, when I trace from my Cisco router it seems to show some MPLS labels after the hop of interest (22.214.171.124 to 126.96.36.199, only 24 msec here!). I'm not sure how our Cisco box derives these from a foreign network.
The ICMP packet (TTL exceeded in transit) contains a copy of the packet which TTL expired, including the labels, so label information is available to traceroute.
