Why Routing list Pref Source get overwritten after adding addresses which are on same network?

Hi,

  1. Whenever we add address in address list it add default entry in Route List and we can’t delete that dynamically created entry.

  2. As shown in following image if we add address 192.168.0.1/24 first and then 192.168.0.2/24
    Then in Route List Pref. Source become 192.168.0.1 as shown in below image.

  3. And if we add address 192.168.0.2/24 first and then 192.168.0.1/24
    Then in Route List Pref. Source become 192.168.0.2 as shown if below image.

    So will it effect on routing behavior? and how to avoid this ?

Thanks..
