1.1 RRPP Overview
Rapid Ring Protection Protocol (RRPP) is an Ethernet ring-specific link layer protocol. It
can not only prevent data loop from causing broadcast storm efficiently when the
Ethernet ring is complete, but also restore communication channels among nodes on
the Ethernet ring rapidly when a link is torn down.
Compared with Spanning Tree Protocol (STP), RRPP features:
z Expedited topology convergence
z Independent of the number of nodes on the Ethernet ring
