I am trying to troubleshoot a latency issue for some of our networks, and was wondering about this.Knowing that routing isn't always symmetrical, is it possible for a traceroute to traverse a different reverse path, than the path that it took to get there? .or will it provide a trace of the path the packet took to reach the destination? According to definition, is should take the same path, but are there any other cases that I should be aware of?
a traceroute shows the outbound route. it's possible for the the probe packets to follow one path and the returning icmp packets to take another path. a looking glass in the AS your tracing to is a good way to see what the return path is... marty -- Close your brown eyes, And lay down next to me.
