[ Switching > L2-Redundancy > MRP ]
The Media Redundancy Protocol (MRP) is a protocol that lets you set up high-availability, ring-
shaped network structures. An MRP ring with Hirschmann devices is made up of up to 100 devices
that support the MRP protocol according to IEC 62439.
If a section fails, then the ring structure of an MRP ring changes back into a line structure. The
maximum recovery time can be configured.
The Ring Manager function of the device closes the ends of a backbone in a line structure to a
redundant ring.
Note:
Spanning Tree
and Ring Redundancy have an effect on each other. Deactivate the
Spanning
Tree
protocol for the ports connected to the MRP ring. See the
Switching > L2-Redundancy > Spanning
Tree > Port
dialog.
