Okay, I'll try to give a good overview of my situation.
What I have going on is 2 different ISP's, with ISP managed routers, each connected to an ASA5505, each connected to a Cisco 2811 router (they are connected to each other as well)
Right now I have glbp going on, but i'm not sure if its setup correctly. Also, I need to track an IP (basically, any IP outside, I wanted to use the provider's IP) to switch over default routes...does this make sense?
Well, things work great when i unplug an ASA or Router, but if the internet stops working on ISP 1 it doesn't seem to failover to ISP 2...This is important because I have 2 VPN tunnels running over each ISP for redundant links.

Right now I have it tracking the reachability. I've read some other things about running a ping using IP SLA? I'm unfamiliar with this...any help would be great.

Anyhow, I really need help finalizing this configuration. I can post if needed, let me know. Thanks in advance.
 
Okay...
Also, I'm using OSPF if that matters...

Do you need to see the ASA configurations too?
thanks again!
 
a topology drawing with all devices in question would be helpful. complete configs of the devices would also be very helpful (attach them as text files using box.net or some other public file sharing site). once we see all of this then we can help you build your solution properly.
