erps ring instance rpl

描述

In ERPS, there is a central node called RPL Owner Node which blocks one of the ports to ensure that there is no loop formed for the Ethernet traffic. The link blocked by the RPL owner node is called the Ring Protection Link or RPL. The node at the other end of the RPL is known as RPL Neighbor Node. It uses R-APS control messages to coordinate the activities of switching the RPL link on and off.

The没有form of this command removes the RPL port configuration from the ERPS ring instance.
