Discovered this wierd routing while investigating horrendously slow speeds (albeit no packet loss) to a particular ISP abroad.Hi Randy, This is per-packet load balancing. In the forward path the alternates are different lengths but the traceroute stops as soon as at least one of the paths reaches the destination. The return path is also engaged in per-packet load balancing but the paths are all the same length.
Seems like a lot of bandwidth trying to save bandwidth. Or does that only happen to ICMP?
