In fact, based on the following, the interfaces can be assigned either to MRP or STP. IE-2000 -8 TC IE-20008 TC IE-2000 -8 TC IE-2000 -8 TC IE-2000 -16 TC MRP-STP Interoperability MRP works with Spanning Tree Protocol (STP) to prevent unwanted broadcast loops in the event that a user accidentally connects a device that does not participate in the MRP ring. In a network operating with MRP and STP, spanning tree BPDUs are not sent on MRP-enabled ports. If ports are unconfigured from an MRP ring, then the ports are added to the spanning tree. MRP-STP interoperability is supported for both PROFINET MRP mode and MRP CLI mode, and functions without additional CLI configuration. ISSUE: if the STP is implemented for the uplinks, the uplinks will both be active and therefore for STP the loop is not there when in reality there is. In fact, from DIG cisco attached to the next slide (pages 3 -8 and 9 -12) the correct single node MRP
