// With the exception of source route options, this data must be in the

// route option should contain the full route - first hop thru final
// destination - in the route data. The first hop will be pulled out of the
// data and the option will be reformatted accordingly. Otherwise, the route
// option should be formatted as specified in RFC 791.
