Example:Configuring Ethernet Ring Protection for MX Series Routers
Thisexample configures Ethernet ring protectionfor three MX Series router nodes:

Router1 (RPL Owner) Configuration on page 149
Router2 Configuration on page 150
Router3 Configuration on page 152

Thelinks connecting the three MX Series routersare shown in Figure 23 on page 148.

Thisexample uses the following topologydetails for Ethernet ring protection:
Router1 is the RPL owner. The node identificationfor Router 1 is MAC address
00:01:01:00:00:01.
TheRPL link is ge-1/0/1.1 (this is also the R-APS messaging control channel).
Trafficflowsamong the nodes in the configured bridge domains. (That is, only the
controlchannels are configured.)
Router1’s east control channel interfaceis ge-1/0/1.1 (the RPL) and the west control
channelinterface is ge-1/2/4.1.The protection group is pg101.
