To reduce Edge-Hello traffic, you can assign Ring 2 and Ring 3 to an RRPP ring group configured on the
edge node Device B, and assign Ring 2 and Ring 3 to an RRPP ring group configured on Device C. After
such configurations, if all rings are activated, only Ring 2 on Device B sends Edge-Hello packets.
Typical RRPP networking
Single ring
As shown in Figure 18, only a single ring exists in the network topology. You only need to define an RRPP
domain.

Tangent rings
As shown in Figure 19, two or more rings exist in the network topology and only one common node exists
between rings. You must define an RRPP domain for each ring.
