1.1 RRPP Overview
The Rapid Ring Protection Protocol (RRPP) is a link layer protocol designed for
Ethernet rings. RRPP can prevent broadcast storm caused by data loops when the
Ethernet rings are healthy, and rapidly restore the communication paths between
nodes after a link is disconnected on the Ethernet ring network.
Compared with the spanning tree protocol (STP), RRPP has the following
characteristics:
z Dedicated to Ethernet ring topology
z Fast response
