loop from occurring while you are configuring MRP on the ring nodes. Once MRP is configured and
enabled on all the nodes, you can re-enable the interface.
• The above configurations can be configured as MRP masters or MRP members (for different rings).
• Brocade does not recommend configuring more than 15 MRP instances on FCX and ICX 6650
devices. Also, due to hardware limitations on this platforms, configuring 40 or more MRP instances
may cause errors.
• If you configure MRP on a device running Layer 3 software, then restart the device running Layer 2
software, the MRP configuration gets deleted.
MRP rings without shared interfaces (MRP Phase 1)
MRP Phase 1 allows you to configure multiple MRP rings, as shown in Figure 2 , but the rings cannot
share the same link. For example, you cannot configure ring 1 and ring 2 to each have interfaces 1/1
and 1/2.
Also, when you configure an MRP ring, any node on the ring can be designated as the master node for
the ring. A master node can be the master node of more than one ring. (Refer to
Figure 2 .) Each ring is
an independent ring and RHP packets are processed within each ring.
