There are two ISP and BGP is configured, I wanted the packets to taken path from One of ISP and return path should to be received from other ISP. How?

used wieght on one router for incoming preference from one router.

use local preference for outgoing traffic.

I am really sorry to tell you that the question is written with terribly poor english (no offense). As a result, i can't get the picutre. I will be glad to post a layout or diagram to get proper answers. Normally, in BGP, an ISP's Autonomous System (AS) is a transit AS, which means it passes traffic (routes) back and forth between customers' AS. If you mean BGP multi-homed design with dual ISPs, let me know.
