摘要： Systems and methods for micro-loop avoidance include detecting a remote link failure in a network and identifying an associated Point of Local Repair (PLR); determining destinations in the network that are impacted due to the remote link failure; and installing of a temporary tunnel to the PLR. The steps can further include sending traffic destined for nodes impacted by the remote link failure via the temporary tunnel to the PLR. The temporary tunnel can be implemented by a node Segment Identifier (SID) for the PLR.
