Viewing DvR routes

About this task

View the DvR routes (IPv4 network routes) on a DvR Controller or a Leaf node.

Controllers display all the IP subnet routes configured for that DvR domain. The Leaf nodes display the IP subnet routes that are learned from the Controller(s) for the Layer 2 VSNs in the DvR Domain. Leaf nodes also display routes that are redistributed by Controllers (direct routes, static routes and the default route), into the DvR domain.

Before you begin

Ensure that you enable DvR globally on the node.

Procedure

Enter Privileged EXEC mode:

enable
View the DvR routes.

On a Controller:

show dvr routes [ipv4 {A.B.C.D}]|[l3isid <0-16777215>]|[nh-as-mac]|[vrf WORD<1-16>]|[vrfids WORD<0-512>]

On a Leaf node:

show dvr routes [ipv4 {A.B.C.D}]|[l3isid <0-16777215>]|[nh-as-mac]

Viewing the DvR routes for a specific VRF or VRF ID is not supported on a DvR Leaf node.

Example

View DvR routes on either a Controller or a Leaf node.

Viewing the DvR routes for a specific VRF or VRF ID is not supported on a DvR Leaf node.
