Hi Nhan, First, I want to make sure you understand the syntax of the distance command in EIGRP. What you have hear will actually set the distance to 90 for any routes sources from 140.112.56.2 and 140.112.56.3. As far as WHAT routes specifically get set to AD of 90, you would need to call an ACL there as well. With this command as you have it ALL routes sourced from either of those addesses will have AD 90.
With that being said, Can you clarify your question a little more? If you want to prefer 1 route over another you need to either change the AD or change the metric. AD you can change with the distance command, but I would also call an ACL to be more specific. Metric you can influence with an offset list, or by mucking about with bandwidth or delay on the relevant interfaces. I hope that helps!
