I assume then conversely your not receiving much traffic via your
primary links and since you say your receiving 500 routes from the
backup provider I'll assume you running BGP and getting partial routes.
If yes to the above your backup provider is better connected or
annoucing a longer prefix. If they are annoucing the same prefix then
try adding a as path prepend to make the backup less desireable.
