Moving a vIST Controller pair from one domain to another

About this task

Use this procedure to move a vIST Controller node pair from one DvR domain to another.

For vIST to work properly, both Controller nodes must be in the same domain.

Procedure

  1. Disable IS-IS on each vIST peer Controller node, to remove the node from the SPB network.

    no router isis enable

  2. Disable DvR on each Controller node:

    no dvr controller

    Caution

    Caution

    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 which you can view using the command show running-config.

  3. Configure each node as a DvR Controller node, with the new domain ID. Ensure that you configure both nodes as Controller nodes and with the same domain ID.

    dvr controller <1–255>

  4. Enable IS-IS on each vIST peer Controller node, to add back the node to the SPB network.

    router isis enable

Example

Consider two vIST peer Controller nodes Switch1 (IP address 51.51.51.3) and Switch2 (51.51.51.4) that belong to a DvR domain (with domain ID 4), that you need to move to another domain (with domain ID 5).

Disable IS-IS globally on each Controller node:

Switch1:1>en
Switch1:1>conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch1:1(config)#router isis
Switch1:1(config-isis)#no router isis enable
Switch1:1(config-isis)#exit
Switch1:1(config)#
Switch2:1>en
Switch2:1>conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch2:1(config)#router isis
Switch2:1(config-isis)#no router isis enable
Switch1:1(config-isis)#exit
Switch1:1(config)#

Disable DvR on each node:

Switch1:1(config)#no dvr controller
Switch2:1(config)#no dvr Controller

Configure each node as a DvR Controller, with domain ID 5.

Switch1:1(config)#dvr controller 5

Switch2:1(config)#dvr controller 5

Enable IS-IS globally on each Controller node.

Switch1:1(config)#router isis
Switch1:1(config-isis)#router isis enable
Switch1:1(config-isis)#exit
Switch1:1(config)#
Switch2:1(config)#router isis
Switch2:1(config-isis)#router isis enable
