Metro Ring Protocol
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.
MRP rings with shared interfaces (MRP Phase 2)
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 42 shows examples of multiple MRP rings that share
the same interface.
