[SR-Users] Re: Dispatcher behavior

Hi Henning, I've been over that section a number of times, but it is still not clear why Dispatcher would return from ds_select_dst a host that is in IP state. "I" is Inactive. What does "Probing" mean? Does it imply something besides "we're trying to send OPTIONS packets"?
