Configure an Isolated Controller on a DvR Isolated Domain

Configuring a node as a DvR isolated Controller enables DvR globally on that node.

Before you begin

  • Ensure that you configure IP Shortcuts on the node.

  • Ensure that the dvr-leaf-mode boot flag is disabled on the node.

    To verify the configuration, enter show boot config flags in Privileged EXEC mode.

About this task

Perform this procedure to create a DvR isolated domain with the domain ID that you specify, and configure the role of the node as an isolated Controller of that domain. For more information about the DvR isolated domain and Restrictions on a DvR Isolated Controller, see DvR Isolated Domains and Restrictions on a DvR Isolated Controller.

Disabling DvR on a DvR Controller destroys the domain ID and all dynamic content learned within the DvR domain. However, the switch retains the VLAN specific configuration and you can view the information using the command show running-config.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Configure an isolated DvR domain ID:

    dvr isolated controller <1-255>

  3. Optional: Disable default route injection for the GRT on an isolated Controller:

    dvr isolated controller <1-255> inject-default-route-disable

  4. View a summary of the Controller configuration:

    show dvr

Examples

Configure a node as a DvR Controller for an isolated domain:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#dvr isolated controller 34
Switch:1>show dvr
