Satish,

appreciate your help.

All your scenarios showing when we have Public AS in all three sites---

Customer place/ISP-A/ISP-B .

But I do not want my OWn site to become Trasit AS for both ISP's. I want to use a Private AS on my Site...which will forward all the internet routes to both ISP's and in return i should get routes from only both ISP AS routes , not all routes like other public AS routes of other ISP whicha re conected from these ISP A & B.

My Current scenario :- I have a single Router conected to dual ISP and looking for auto failure for these scenario when one link goes down.

Thanks.
