Huawei Quidway S6700 series User Manual

3.4.1 Establishing the Configuration Task
RRPP does not support auto-selection mechanism. Therefore, you need to correctly configure
each node on the ring to achieve detection and protection of the ring.
Applicable Environment
RRPP multi-instance can be applied to a more complicated networking. As shown in Figure
3-4, two RRPP sub-rings are formed after CEs are dual-homed to UPEs, and an RRPP ring is
constructed by four UPEs and one PE-AGG. The PE-AGG delivers the user data to the backbone
network.
