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.
no router isis enable
no dvr leaf
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.
Ensure that you configure both nodes as Leaf nodes and with the same domain ID.
dvr leaf <1–255>
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>
router isis enable
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).
