This disclosure provides robust and generalized algorithms that allow prevention of micro-loops directly on the post-convergence path following a link failure (Link down) or upon re-convergence following a newly inserted link in the topology (Link up). Through this solution, if a remote link fails, traffic can leverage emulated local loop-free backup calculations on behalf of the PLR nodes without explicitly redirecting traffic to the PLR and instead directly tunnel traffic to reach the destination directly on the post convergence path (after the link churn) through a loop-free intermediary node (in a loop-free manner) during convergence, thus resulting in minimal to no traffic loss due to micro-loops on any link on the post convergence path.
