I did a test that involves 3 computers:
Machine A - Windows IP 9.53.23.38 sending ICMP ping requests
Machine B - Windows IP 9.48.150.77 receiving ICMP ping requests
Machine C - Linux machine on the same bridge as Machine A and can see
all traffic to/from Machine A
Running wireshark on machine A shows duplicate ping requests.
Running wireshark on machine B shows no duplicates, but shows ping
requests/replies
Running wireshark on machine C shows no duplicates.
One thing I note:
The destination MAC address of the ping request is
All-HSRP-Routers_01 (00:00:0c:07:ac:01).
(After doing a little research): the use of HSRP destination MAC address
is just how the HSRP stuff works so that's probably not particularly
relevant.
Instead: Please see
http://wiki.wireshark.org/CaptureSetup/InterferingSoftware and check if
anything mentioned there is relevant.
