The main reason I prefer ISIS is that it uses CLNS packets for communications and we don't route CLNS. (I don't think ANYONE is routing CLNS today.) That makes it pretty secure.
Unless, of course, someone one hop away -- a peer? a customer? an upstream or downstream? someone on the same LAN at certain exchange points? -- sends you a CLNP packet at link level... --Steve Bellovin, http://www.cs.columbia.edu/~smb
