Chapter 14 Configuring Resilient Ethernet Protocol
Configuring Resilient Ethernet Protocol (REP)
Setting Manual Preemption for VLAN Load Balancing
If you do not enter the rep preempt delay seconds interface configuration command on the primary edge
port to configure a preemption time delay, the default is to manually trigger VLAN load balancing on
the segment. Be sure to complete all other segment configuration before manually preempting VLAN
load balancing. When you enter the rep preempt segment segment-id command, a confirmation
message appears before the command is executed because preemption can cause network disruption.
Note Do not configure VLAN load balancing on an interface that carries Ethernet over MultiprotocolLabel
Switching (EoMPLS) traffic. VLAN load balancing across the REP ring might prevent forwarding some
of the EoMPLS traffic.
