Abstract:
   This document describes a mechanism for link-state routing protocols
   to prevent local transient forwarding loops in case of link failure.
   This mechanism proposes a two-steps convergence by introducing a
   delay between the convergence of the node adjacent to the topology
   change and the network wide convergence.

   As this mechanism delays the IGP convergence it may only be used for
   planned maintenance or when fast reroute protects the traffic between
   the link failure time and the IGP convergence.

   The proposed mechanism will be limited to the link down event in
   order to keep simplicity.

   Simulations using real network topologies have been performed and
   show that local loops are a significant portion (>50%) of the total
   forwarding loops.
