Application of Tangent RRPP Rings of Multi-Instance on a MAN

Application of Tangent RRPP Rings of Multi-Instance on a MAN

In Figure 18-26, two RRPP rings (ring 1 in domain 1 and ring 1 in domain 2) are configured on the five UPEs on the CE (left) side. One RRPP ring (ring 1 in domain 3) is configured on the four UPEs on the right side.

Figure 18-26  Tangent RRPP rings of multi-instance in a MAN

Domain 1 processes data in VLANs 101 to 200, Domain 2 processes data in VLANs 1 to 100, and Domain 3 processes data in VLANs 1 to 200.

The RRPP ring on the left side implements master/slave protection and load balancing for the Layer 2 services in VLANs 1 to 200. When all the nodes and links on the RRPP rings are working properly, traffic sent to rings from CEs is transmitted along different paths according to the service VLAN, implementing traffic load balancing.

Traffic in VLANs 1 to 200 flows from the tangent node into the RRPP ring on the right side.
