How does the absence of an IXP route affect traceroutes -through- it? The IXP device has a route back to the source of the trace, so it can reply. The traceroute packets are addressed to the ultimate destination, so they don't need the IXP route.
Quite a few GUI traceroute products expect to be able to ping each hop, and produce statistics based on that...definitely a bad approach, particularly utilizing ICMP, but that's the common practice. I cannot count the number of tickets I've seen opened because someone didn't know how to properly interpret traceroute data. --msa
