Hi Vaib,

"i have also same router and two ISP bandwith with BGP routing, i also need load sharing between both ISP and failover when one ISP Bandwoth"

- Am I right assuming that you are running BGP between your 2821 router and two ISPs and receive default routes from both ISP?. If so, enabling BGP multipath will install both the default routes (assuming all BGP attributes are same for both default prefix) into your routing table. Load balancing and failover will be taken care if you have 2 default entry in your routing table.

IP SLA is a IOS inbuilt tool that can be used for measuring network performance.Below is the link for IP SLA configuration guide,
