Configuring Cisco Proprietary Resilient
Packet Ring
Note
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This chapter describes how to configure Cisco proprietary resilient packet ring (RPR) and Cisco
proprietary RPR Link Fault Propagation.
