Metro Ring Protocol (MRP)

Configuration notes

• When you configure MRP, Brocade 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.

• MRP 1 and MRP 2 support are added for the devices.

• The above configurations can be configured as MRP masters or MRP members (for different

rings).

• On TurboIron X Series platforms, you can configure maximun of 32 metro rings.

MRP rings without shared interfaces (MRP Phase 1)

MRP Phase 1 allows you to configure multiple MRP rings, as shown in Figure 8, but the rings

cannot share the same link. For example, you cannot configure ring 1 and ring 2 to each have

interfaces 1 and 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 Figure 8.) Each

ring is an independent ring and RHP packets are processed within each ring.

FIGURE 8 Metro ring – multiple rings

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.
