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 154
• Router 1 (RPL Owner) Configuration on page 155
• Router 2 Configuration on page 157
• Router 3 Configuration on page 158
Example Topology
The links connecting the three MX Series routers are shown in Figure 23 on page 154 .

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 .
