Re: IGP metrics on WAN links

Think most ISPs use actual fiber miles (with an arithmetic factor to get to
a certain range of course) as the means for the value of IGP metrics... of
course there are always some "twinking" done regularly to give higher
priorities to the higher bandwidth, link condition etc.
