27.3.1 Working Procedure of MEAPS
MEAPS adopts three protection mechanisms to support the single-ring or evel-2 multi-ring structure. The
following sections shows, from the complete state to the link-down state, then to recovery and finally to the
complete state again, the details of MEAPS running and the change of the MEAPS topology by typical
examples.
27.3.2 Complete state
The complete state of the ring, which is advocated for only one ring, is monitored and maintained by the
polling mechanism. In complete status, all links on the whole ring are in UP state, which finds expression in
the state of the master node. In order to prevent the broadcast storm from occurring, the master node will
