Re: L0pht ICMP Router Discovery Advisory

An addendum to the Microsoft IRDP implementation.  Its somewhat broken in that its mapping of IRDP preference to 
routing metric is not monotonically decreasing ie. high-preference/hi-priority routes are actually treated as low 
priority routes.  Here are the mappings I found on my win98 machine.
