redundancy

I'm trying to set up a redundant connection for our web hosting servers. I have a BGP-capable router connecting two lines from two separate ISP's, one fiber (primary), one DSL (failover). I've already confirmed that I can push routes into the DSL ISP's system, so long as they aren't malicious. My question is, what do I need to do on the fiber side to make those IP's routable through the DSL? Is there something I'm missing?
