View DvR Backbone Entries

About this task

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

Note

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

  1. Enter Privileged EXEC mode:

    enable

  2. View DvR backbone entries:

    show dvr backbone-entries [adv-controller WORD<1-255>]|[domain-id <1-255>]|[home]|[host-mac-address 0x00:0x00:0x00:0x00:0x00:0x00]|[ipv4 {A.B.C.D}]|[l2isid <1-16777215>]|[l3isid <0-16777215>]|[next-hop WORD<1-255>]|[nh-as-mac]|[remote]

Example

View all DvR backbone entries:
