MRP Phase 2
MRP phase 2 expands functionality by allowing a physical interface to be shared by multiple rings
configured within the same vlan.
Recall that in MRP Phase 1, a node can have multiple MRP rings, but the rings cannot share the
same interface. Any node can be designated as the master node for the ring. Each ring is an
independent ring and RHP packets are processed within each ring exclusively.
FIGURE 114 Multiple MRP rings - phase 1
With MRP phase 2 multiple rings can be configured to share the same interface as long as the
interfaces belong to the same vlan.
Figure 115 shows an example of two rings that share the same
interfaces on S1 and S2.
