About This Chapter
The Rapid Ring Protection Protocol (RRPP) features fast convergence, because the convergence
time is irrelevant to the number of the nodes on the ring. In addition, RRPP multi-instance
supports load balancing of different types of traffic.
3.1 Overview of RRPP
RRPP is a link layer protocol applied to an Ethernet ring. RRPP features fast convergence and
can prevent broadcast storms caused by data loops.
3.2 RRPP Features Supported by the S3700
This section describes the RRPP features supported by the S3700.
3.3 Configuring RRPP Functions
Through RRPP, devices on an Ethernet ring are configured to be the nodes with different roles
on RRPP rings. The nodes on an RRPP ring detect the ring status and transmit topology changes
by sending and receiving RRPP protocol packets. The master node on an RRPP ring blocks or
opens secondary ports according to the ring status. In this manner, if a fault occurs on a node or
a link on the RRPP ring, traffic can be fast switched to the backup link and data loops can be
prevented.
3.4 Configuring RRPP Multi-Instance
RRPP multi-instance is based on domains. Multiple RRPP domains can be configured on a
physical ring. In a domain, all ports, nodes, and topologies must comply with basic RRPP
principles. Therefore, a physical ring has multiple master nodes. Each master node independently
detects the completeness of the physical ring and blocks or unblocks its own secondary ports
accordingly.
3.5 Maintaining RRPP
Commands of clearing statistics helps to locate the RRPP faults on a device.
3.6 Configuration Examples
This section provides several configuration examples of RRPP.
