Precautions before Configuration:
z The RERP and STP are exclusive. In other words, if the RERP is configured, the
STP shall be turned off. RERP and REUP cannot share a port.
z The refresh failure waiting time and the detection failure time are always the same
and equal to the failure time.
z If the Transit and Backup do not receive the HELLO message from the Master,
they will use the detection interval and detection failure interval that are
configured on the local machine. If the HELLO message is received from the
master, the master configurations will be used to keep consistent protocol
operations on the ring network.
z The RERP control VLAN does not include vlan 1 and vlan 4094.
z Each RERP region must have one and only one master and at the same time at
most one backup.
