MRP rings without shared interfaces (MRP Phase 1)

MRP Phase 1 allows you to configure multiple MRP rings, as shown in Figure 1, but the rings cannot share the same link. For example, you cannot configure ring 1 and ring 2 to each have interfaces 1/1/1 and 1/1/2.

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 1.) Each ring is an independent ring and RHP packets are processed within each ring.

Figure 1. Metro ring - multiple rings

In this example, two nodes are each configured with two MRP rings. Any node in a ring can be the master for its ring. A node also can be the master for more than one ring.
