3.2.2. DODAG Repair

A DODAG root institutes a global repair operation by incrementing the DODAGVersionNumber. This initiates a new DODAG Version. Nodes in the new DODAG Version can choose a new position whose Rank is not constrained by their Rank within the old DODAG Version.

RPL also supports mechanisms that may be used for local repair within the DODAG Version. The DIO message specifies the necessary parameters as configured from and controlled by policy at the DODAG root.
