II. Multi-domain tangent rings
Master node
Domain 1
Figure 1-3 Multi-domain tangent rings
There are two or more rings in the network topology and only one common node
between rings. In this case, you need define an RRPP domain for each ring.
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.
