LDP session protection helps maintain LDP adjacencies but does not provide the explicit, pre-calculated fast reroute capabilities for MPLS TE tunnels necessary for sub-50ms convergence in case of link or node failures.

MPLS TE Fast Reroute (FRR) with node protection provides rapid local convergence by pre-establishing backup LSPs that completely bypass a failed node (and its attached links), thus delivering faster MPLS-enabled convergence, which is ideal in an OSPF TE environment for high availability.

While MPLS TE Fast Reroute link protection is a valid FRR method, node protection offers more comprehensive failure coverage by protecting against an entire node failure, which implicitly includes its attached links, making it a generally more robust solution for overall network resilience.

OSPF Loop-Free Alternate (LFA) Fast Reroute is an IGP-based rapid convergence mechanism, but the question specifically asks for 'MPLS-enabled convergence,' which points to MPLS TE FRR when TE capabilities are present.
