1.1.3 Typical RRPP Networking

Here are several typical networking applications.

I. Single ring

Ring 1

Transit node

Figure 1-2 Single ring

There is only a single ring in the network topology. In this case, you only need to define

an RRPP domain.

II. Multi-domain tangent rings

Ring 2

Ring 2

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.
