Abstract
Techniques of this disclosure enable loop protection for networks that utilize hop-by-hop routing, such as networks that utilize multi-protocol label switching (MPLS) label distribution and interior gateway protocol (IGP) routing. As described herein, the techniques provide protection from any small transient loops that may emerge due to link failure or other topology change events in networks that utilize hop-by-hop routing techniques.
