Hi, in that case try 0.0.0.0 0.0.0.0 1.1.1.1 on both switches.at the moment no redundancy on your environment.
we are connecting links on two Dell L3 switches. Dell Switches configured VLTi. diagram as attached.  Our issue is while we are connecting second inap link to Dell-2, it;s impacting Dell-1 traffic. when we remove the second link, primary link is working fine. VLANs created on both switches.  [IMAGE]   can you please confirm what could issue?
