The most common place where I have encountered that would involve differing AUPs on different links. For example, if one has a link which is built on an amateur radio layer 1, one cannot carry commercial, pornographic, encrypted, or certain other kinds of traffic on that link. I believe Internet2 vs. public transit may also pose some such requirements. Other situations I’ve seen involve data privacy concerns and/or security zone issues. Common? Not in my experience. Usually done with a combination of ACLs, Routing Policy, etc. Owen

to make the case that in some scenarios it is very important for a network operator to be able to specify that traffic should *not* traverse a certain switch/link/group of switches/group of links (that's true right?). Could you give some examples? Perhaps point me to relevant references?
if so, why? security? congestion? other? but is it common? and, if so, how do you do it?
