Understanding RPR-IEEE

RPR, as described in IEEE 802.17, is a metropolitan area network (MAN) technology supporting data
transfer among stations interconnected in a dual-ring configuration. The IEEE 802.17b spatially aware
sublayer amendment is not yet ratified but is expected to add support for bridging to IEEE 802.17. Since
the amendment is not yet ratified, no equipment is currently IEEE 802.17b compliant. The ML-Series
card's RPR-IEEE is based on the expected IEEE 802.17b based standard.
The ML-Series card supports RPR-IEEE. RPR-IEEE is well suited for transporting Ethernet over a
SONET/SDH ring topology and enables multiple ML-Series cards to become one functional network
segment. When used in this role, RPR-IEEE overcomes the limitations of earlier schemes, such as
IEEE 802.1D Spanning Tree Protocol (STP), IEEE 802.1W Rapid Spanning Tree Protocol (RSTP), and
SONET/SDH.
Throughout this book, Cisco proprietary RPR is referred to as Cisco proprietary RPR, and
Note
IEEE 802.17b-based RPR is referred to as RPR-IEEE. This chapter covers RPR-IEEE.
