Correct answer & explanation
✓
It is disabled by default and is used in Phase 3 to enable NHRP redirects.
In DMVPN Phase 2, the 'ip nhrp redirect' command is not enabled by default on the hub. It is used in Phase 3 to enable NHRP redirects, which allow the hub to inform spokes that a better path exists directly to another spoke. In Phase 2, spoke-to-spoke tunnels are established based on NHRP resolution triggered by traffic, not by redirect messages.
