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.
