MRP rings without shared interfaces (MRP Phase 1)
MRP Phase 1 allows you to configure multiple MRP rings, as shown in
cannot share the same link. For example, you cannot configure ring 1 and ring 2 to each have
interfaces 1/1 and 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
Each ring is an independent ring and RHP packets are processed within each ring.
FIGURE 59
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.

When you configure MRP, Dell recommends that you disable one of the ring interfaces before
beginning the ring configuration. Disabling an interface prevents a Layer 2 loop from occurring
while you are configuring MRP on the ring nodes. Once MRP is configured and enabled on all
the nodes, you can re-enable the interface.
The above configurations can be configured as MRP masters or MRP members (for different
rings).
