Viewing DvR backbone entries
About this task
View the DvR backbone entries (redistributed host routes) learned from all Controllers in all DvR domains.

Note
DvR backbone entries can be viewed only on a Controller. Viewing backbone entries is not applicable on a Leaf node.
Before you begin
Ensure that you enable DvR globally on the node.
Procedure
Example
