Expanding a VC by adding a new IMM-only node

This scenario is similar to Replacing an IMM-only node with another node except that instead of replacing an existing IMM-only node, a new node is being added. This requires the configuration file on the active CPM to be updated by adding the new IMM-only node VC configuration parameters using the config>system>vc-stack>vc-stack-node command, without deleting or modifying any existing VC configuration parameters.
