MRP phase 2

In MRP Phase 1, a node can have multiple MRP rings, but the rings cannot share the same
interface. Also, when you configured an MRP ring, any node on the ring that is a device can be
designated as the master node for the ring. Each ring is an independent ring and RHP packets are
processed within each ring.
FIGURE 70 Multiple MRP rings - MRP Phase 1
With MRP Phase 2, MRP rings can be configured to share the same interfaces as long as the
interfaces belong to the same VLAN.
Figure 70 shows examples of multiple MRP rings that share
the same interface.
