(Related to this question I posted a while ago on apple.stackexchange.)
What is the difference between the following two routing table entries:
default E.F.G.H UGSc 0 0 en1 default E.F.G.H UGScI 25 0 en1
(Where E.F.G.H is some gateway IP address.) Specifically what effect does the
RTF_IFSCOPE flag have on the routing table entry?
