    To quote from cisco's web page:

    http://www.cisco.com/warp/public/105/ext_ping_trace.html

    The Extended ping Command

            When a normal ping command is sent from a
            router, the source address of the ping is the IP
            address of the interface that the packet uses to exit the router.
            If an extended ping command is used, the source IP address
            can be changed to any IP address on the router. The extended
            ping is used to perform a more advanced check of
            host reachability and network connectivity.

    The poster will note that the source address for a ping is not
    necessarily the same as the source address for an extended ping, and
    should be able to extrapolate a solution from this data.

    [specifics about the posters setup deleted, as the proof is trivial,
    and is left to the reader]

    cheers!
