Hi,

You might want to look at static route tracking with sla monitor. You can use icmp to ping an ip address to ISP1 and if ASA sees a drop in ping reply it would populate a backup route in the routing table.

Hi Thiru,

Yes, if you configure it as per the doc, whenever ISP1 fails, all the traffic including http, would go through your ISP2 only.
