Example: Configuring Ethernet Ring Protection for MX Series Routers

Example Topology

148
This example configures Ethernet ring protection for three MX Series router nodes:
Example Topology on page 148
Router 1 (RPL Owner) Configuration on page 149
Router 2 Configuration on page 150
Router 3 Configuration on page 152
The links connecting the three MX Series routers are shown in

This example uses the following topology details for Ethernet ring protection:
Router 1 is the RPL owner. The node identification for Router 1 is MAC address
.

The RPL link is ge-1/0/1.1
Traffic flows among the nodes in the configured bridge domains. (That is, only the
control channels are configured.)
