3.2 Example of MRP-Ring
A network contains a backbone in a line structure with 3 devices. To increase
the redundancy reliability of the backbone, you have decided to convert the
line structure to a ring redundancy. In contrast to the previous example,
devices from different manufacturers are being used which do not all support
the HIPER-Ring protocol. All the devices have MRP as the ring redundancy
protocol, so you decide to use MRP. You use ports 1 and 2 in module 1 of
the devices to connect the lines.

The following example configuration describes the configuration of the ring
manager device (1). You configure the two other devices (2 to 3) in the same
way, but without activating the ring manager function. This example does not
use a VLAN. You have entered 200 ms as the ring recovery time, and all the
devices support the advanced mode of the ring manager.
