ASA 5540 - two ISP's and I want to use both and failover

I will be working on an ASA5540 and here is what I would like to do. We have 2 separate ISP providers, one 20Mb and the other 20Mb as well but could be moving to 50Mb, and we want to use both circuits all the time and if one circuit fails everything goes over the remaining circuit. I have done this with a router using IP SLA with interface tracking and Policy Based Routing to send some traffic over one circuit and others over the second circuit. What I would like to know is what is the best way to accomplish what I need and can the ASA do IP SLA and PBR or is there a better way to do this?

  

Thanks,

Mike

Unfortunately you can only achieve half what you can achieve on the router with an ASA.

ASA can do IP SLA, however, it can't do PBR and neither can it have 2 default gateways configured going to 2 different ISP.

For IP SLA on ASA, here is a sample config:

Thanks for your help. It is a little disappointing and surprising there is now way to do this.
