Ethernet Ring Overview and Topology
This section describes a configuration example for a three-node ring. The ring topology
is shown in Figure 17 on page 120.

node 3
The configuration in this section is only for the RAPS channel. The bridge domain for user
traffic is the same as the normal bridge domain. The only exception is if a bridge domain
includes a ring port, then it must also include the other ring port of the same ring.
Configuring a Three-Node Ring
To configure Ethernet Ring Protection Switching on a three-node ring, perform these
tasks:
