The RRPP (Rapid Ring Protection protocol) provides fast protection switching to layer 2 switches interconnected in an Ethernet ring topology. When a link in the ring breaks, the RRPP can recover the data path quickly. Its protection switching is similar to what can be achieved with the Spanning Tree Protocol (STP), but the converging time is less than a second after link failure. This MIB defines management information used on products which support RRPP.
