I hadn't used this feature before either, but it certainly got me
interested so I configured a router to do "ip traffic export".
Unfortunately my test-setup was limited so I could not route
traffic *trough* the box. But I was able to see the incoming
packets as they were forwarded to the wireshark-pc by the router.
No additional headers were present. So basically the L2 layer
was replaced by "<wireshark-pc-mac><cisco-router-mac>0800".
Could you indeed post a capture with a few frames that show the
extra header?
Cheers,
Sake
