{

For the RPR station to forward traffic, before binding two RPR physical ports with the same RPR

logical interface, you must connect their mate ports.

{

You can bind any type of RPR physical ports to an RPR logical interface. However, the RPR
physical ports bound to an RPR logical RPR interface must be of the same type.

RPR master/slave port

The first RPR physical port bound to the RPR logical interface is the master port, and the second RPR

physical port bound to the RPR logical interface is the slave port.
All calculation concerning the operation of RPR is done on the master port, and the calculation result is
synchronized to the slave port for consistency. Examples of RPR-related calculation include execution of

configuration commands, protection event processing, and RPR frames sending for topology discovery.
When the master port fails or leaves the binding with the RPR logical interface, the slave port takes over

as the master port.
