View DvR Database Information
Before you begin
Ensure that DvR is enabled globally on the node.
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 Layer 2 VSNs in the DvR Domain. It also displays the Host Routes (ARPs) learned from other DvR enabled nodes.
Procedure
- View the DvR database.
On a Controller:
show dvr database [home]|[ipv4 {A.B.C.D}]|[l3isid<0-16777215>]|[nh-as-mac]|[remote]|[vrf WORD<1–16>]|[vrfids WORD<0–512>]
On a Leaf node:
show dvr database [home]|[ipv4 {A.B.C.D}]|[l3isid<0-16777215>]|[nh-as-mac]|[remote]
Note
Viewing the DvR database for a specific VRF or VRF ID is not supported on a DvR Leaf node.
Example
View the DvR database on either a Controller or a Leaf node.
