It’s an indirect attack, it Occurs when malicious node publishes a higher version number of a DODAG tree.This repair take place when network inconsistent can’t be repaired by local repair mechanisms. It’s triggered by the DODAG root incrementing the DODAG version number to initiate a new DODAG version.
