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.
To configure Ethernet Ring Protection Switching on a three-node ring, perform these
tasks:
• Configuring Ethernet Ring Protection Switching on a Three-Node Ring on page 444
