That's because it is unable to route all the nets.  It will frequently
  be impossible to route all the nets in a single layer, and like I
said, eagle's router isn't very good at solving that problem even for
cases where it IS possible.  Successfully making circuits that are
routable in one layer is quite an art, involving gate and pin swapping
as well as laying down tracks.  About the most I hope for from Eagle's
autorouter is to point out sections that are particularly problematic.
You can then manually route the remaining signals, or start with
manually routing some signals and let the autorouter finish...

When you're in the route dialog box, there is either a button or a menu
item for "loading" a set of route rules.
