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
, 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
.) 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.
