Metro Ring Protocol (MRP)

For each discrete ring one node is configured in the master role for the MRP ring. One of the two
ring interfaces on the master node is configured as the primary interface, the other is the
secondary interface. The primary interface originates Ring Health Packets (RHPs) which are used
to monitor the health of the ring. An RHP is forwarded on the ring to the next interface until it
reaches the secondary interface of the master node. On receipt of an RHP the secondary interface
transitions into blocking mode to prevent a layer 2 loop.

Table 62

displays the individual Brocade devices and the MRP features they support.

NOTE

When you configure MRP, it is recommended that you disable the secondary ring interface on the
master node before beginning or changing the ring configuration. Disabling an interface prevents a
layer 2 loop from occurring while you are configuring MRP on the ring nodes. Once you have
completed the MRP configuration and enabled it on all the nodes, you should re-enable the
secondary ring interface.
