III. Single-domain intersecting rings
Figure 1-4 Single-domain intersecting rings
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 set one ring as the
primary ring and other rings as subrings.
IV. Dual homed rings
