Figure 1-2 Schematic diagram for a single-ring network 

 

 

As shown in 

, there are two or more rings in the network topology and only one common node 

between rings. In this case, you need to define an RRPP domain for each ring.  

Figure 1-3 Schematic diagram for a tangent-ring network 

 

 

As shown in 

, there are two or more rings in the network topology and two common nodes 

between rings. In this case, you only need to define an RRPP domain, and configure one ring as the 

primary ring and the other rings as subrings.
