Avoiding loops by preventing further fast reroute (FRR) after an earlier FRR

Abstract:

In some cases, once Fast Reroute (FRR) has taken place (e.g., for MPLS protection), a further FRR is undesirable, and even detrimental. A mechanism to prevent a further FRR, once such a further FRR is determined to be potentially harmful, is described.
