Require Join Existing ** Format: b

• Default Value: false
• This flag is typically used for nodes that are associating with an
• existing network for the first time. If this is set to true before
• PROP_NET_STACK_UP is set to true, the
• creation of a new partition at association is prevented. If the node
• cannot associate with an existing partition, PROP_LAST_STATUS will
• emit a status that indicates why the association failed and
• PROP_NET_STACK_UP will automatically revert to false.
• Once associated with an existing partition, this flag automatically
• reverts to false.
• The behavior of this property being set to true when
• PROP_NET_STACK_UP is already set to true is undefined. */
