Ring Redundancy

3.2 Example of a MRP-Ring

A network contains a backbone in a line structure with 3 devices. To increase
the availability of the backbone, you decide to convert the line structure to a
redundant ring. In contrast to the previous example, devices from different
manufacturers are used which do not all support the HIPER-Ring protocol.
However, all devices support MRP as the ring redundancy protocol, so you
decide to deploy MRP. You use ports 1.1 and 2.2 of the devices to connect
the lines.

The following example configuration describes the configuration of the ring
manager device (1). You configure the 2 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.
