Intersecting rings
As shown in Figure 16, two or more rings are in the intersecting-ring network topology, with two common
nodes between rings. You only need to define an RRPP domain and configure one ring as the primary
ring and the other rings as subrings.

Dual-homed rings
As shown in Figure 17, two or more rings are in the dual-homed rings network topology, with two similar
common nodes between rings. You only need to define an RRPP domain and configure one ring as the
primary ring and the other rings as subrings.
