After you have established that a DLR is present and healthy and it has all the LIFs, the next thing to check is the routing table.
- From the NSX Manager shell, run show cluster all to get the cluster ID.
- Run show cluster cluster-id to get the host ID.
- Run show logical-router host hostID dlr all brief to get the dlrID (Vdr Name).
- Run show logical-router host hostID dlr dlrID route to get the status information for all interfaces.

Points to note:
- “Interface” shows the egress LIF that will be selected for the corresponding “Destination." It is set to the “Lif Name” of one of the DLR’s LIFs.
- For ECMP routes, there will be more than one route with the same Destination, GenMask, and Interface, but a different Gateway. Flags will also include “E” to reflect the ECMP nature of these routes.
