Moving a vIST Leaf node pair from one domain to another

About this task

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

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

Procedure

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

    no router isis enable

  2. Disable DvR on each Leaf node.

    no dvr leaf

    Caution

    Caution

    Disabling DvR on a Leaf node in a vIST pair automatically removes all vIST configuration on that node, but not on the pair. The node on which DvR is disabled also loses its membership with the DvR domain and all the dynamic content learned from the Controllers in that domain.

    When you re-enable DvR on the node, you must manually configure vIST on that node again.

  3. Configure each node as a DvR Leaf node, with the new domain ID.

    Ensure that you configure both nodes as Leaf nodes and with the same domain ID.

    dvr leaf <1–255>

  4. Configure vIST on the DvR Leaf nodes.

    dvr leaf virtual-ist {<A.B.C.D/X|<A.B.C.D> <A.B.C.D>} peer-ip {A.B.C.D} cluster-id <1–1000>

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

    router isis enable

Example

Consider two vIST peer Leaf nodes Switch1 (IP address 51.51.51.1) and Switch2 (51.51.51.2) that belong to a DvR domain (with domain ID 4), that you need to move to another domain (with domain ID 5).

Disable DvR on each node. This automatically removes all vIST configuration on the node, but not on the vIST pair. The node also loses its membership with the DvR domain and all the dynamic content learned from the Controllers in that domain.

Switch1:1(config)#no dvr leaf
Switch2:1(config)#no dvr leaf

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

Switch1:1(config)#dvr leaf 5

Switch2:1(config)#dvr leaf 5

Configure vIST on each of the DvR Leaf nodes.

Switch1:1(config)#dvr leaf virtual-ist 51.51.51.1 peer-ip 51.51.51.2 cluster-id 255
Switch2:1(config)#dvr leaf virtual-ist 51.51.51.2 peer-ip 51.51.51.1 cluster-id 255
