    NSX Edge - ECMP

      Below is the diagram of the setup.

      Edge Gateway in Active- Standby with ECMP enabled.

      The cost is of 1 in both NSX side & Router side.

      So 2 equal paths from Edge Gateway to Physical routers

       

      So the traffic flows through both the paths.

      Now I want to isolate the traffic flowing through VLAN 101 for maintenance purpose.

      Traffic should only flow through vlan 100

      How should I do it.

      I don't want to have any traffic interruption.

       

      Is the below steps correct.

      Step 1. Disable ECMP - Not sure doing this will have any impact

      Step 2 : Change OSPF cost from 1 to 100 in both NSX side & R2 side for VL:AN 101

       

      This should isolate the  traffic flowing through 101

       

      OR

       

      Step 1 : Change OSPF cost from 1 to 100 in both NSX side & R2 side for VL:AN 101 - No need to disable the ECMP

       

      Let me know what is the right step.
