Metro Ring Protocol (MRP)
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 9 shows examples of multiple MRP rings that share the
same interface.
FIGURE 9 Examples of multiple rings sharing the same interface - MRP Phase 2
On each node that will participate in the ring, you specify the ring ID and the interfaces that will be
used for ring traffic. In a multiple ring configuration, a ring ID determines its priority. The lower the
ring ID, the higher priority of a ring.
A ring ID is also used to identify the interfaces that belong to a ring.
