Multiple response for hop in traceroute


When I do a traceroute I get multple responses for certain hops as in example:

  1 0 msec 24 msec 4 msec

  2 0 msec 12 msec 12 msec

  3 20 msec 4 msec 0 msec

  4 0 msec 0 msec 4 msec

  5 4 msec 4 msec 0 msec

  6 4 msec 4 msec 4 msec

Now in hop 2 I understand that there are multiple equal weight routes. This represents our redundant switches. I don't know why the address comes up twice though. I've seen it before and just accepted it until I was showing a new kid and he asked but I don't have the answer for it. Why does the traceroute from Cisco devices pick up the redundant route? Does it function differently than a traceroute from Windows or Linux?

It's funny how after awhile of doing things you just accept it as normal but I can't explain something that should be very basic.

Believe hop 2 is just round-robin.  Try increasing your trace probes up from 3 and check results.
