IP options are annoying in big fast routers because they have to take the slow route via CPU. As there's not
a lot of use in accepting packets (externally at least) with IP options, they tend to be dropped totally (but will almost certainly be policed aggressively to the CPU as the CPU is not good for moving many packets).
