Viewing DvR database information
About this task
View all DvR routes on a Controller or a Leaf node.
The Controller node displays all the IP subnet routes configured for that DvR domain. A Leaf node displays all IP subnet routes learned from the Controller(s) for the L2 VSNs in the DvR Domain. It also displays the Host Routes (ARPs) learned from other DvR enabled nodes.
Before you begin
Ensure that DvR is enabled globally on the node.
Procedure
Example
View the DvR database on either a Controller or a Leaf node.
Viewing the DvR database for a specific VRF or VRF ID is not supported on a DvR Leaf node.
