Example: Configuring Ethernet Ring Protection for MX Series Routers
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
Example Topology
The links connecting the three MX Series routers are shown in Figure 23 on page 148.

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
00:01:01:00:00:01.
•
The RPL link is ge-1/0/1.1 (this is also the R-APS messaging control channel).
•
Traffic flows among the nodes in the configured bridge domains. (That is, only the
control channels are configured.)
•
Router 1’s east control channel interface is ge-1/0/1.1 (the RPL) and the west control
channel interface is ge-1/2/4.1. The protection group is pg101.
