take a look at the columns to the right of the routes. thats the admin distance being specified. they are reversed between

the two wan routers. This will set the preference, in that while both route prefixes are advertised, their preferences are different.

Whit this will do is, assume router 1 fails, the necessary routes are already in the router two table. its a neat little reduncancy scheme.
