Correct answer & explanation
✓
Configure backup tunnel on PLR
MPLS FRR begins with configuring the backup tunnel on the PLR. The PLR then merges the backup tunnel with the protected LSP. When a link or node failure is detected, the PLR immediately switches traffic to the backup tunnel. After the failure is repaired, traffic reverts to the primary LSP via make-before-break.
