Figure 5-68 shows that each link is operating properly, the ring is in idle status, and the
secondary port of the primary node is blocked. Traffic passes through switches C and D.
Figure 5-69 shows that the link between switches B and C is disconnected. The link status
changes to Protection, and ERPS immediately switches the RPL port of the owner node
to forwarding status. After the switching, traffic does not pass through switches C and D.
After the link between switches C and D is restored, the RPL port of the owner node is
blocked again, and the ring status changes to pending as shown in Figure 5-68.
