Hi cfabeny,

Thank you for immediate response.

Can you give me some example abt the functionality of source based routing with diagram.

Well, I can try. consider the following:

1.1.1.1--- A -----10.1.1.1

|---Router---|

1.1.1.2--- B -----11.1.1.1

We have two hosts on the same LAN (1.1.1.1 and 1.1.1.2). The default routing table says all routes destined for 10.1.1.x go out interface A (regardless of source). Now, you could configure source-based routing to say any routes from 1.1.1.2 be sent out interface B -- possibly for a specific NAT translation for example. This is policy-based routing.
