◆ When a secondary ring detects a topology change, it can pass a
message about this event to the major ring. When the major ring
receives this kind of message from a secondary ring, it can clear the
MAC addresses on its ring ports to help the second ay ring restore its
connections more quickly through protection switching.
◆ When the MAC addresses are cleared, data traffic may flood onto the
major ring. The data traffic will become stable after the MAC addresses
are learned again. The major ring will not be broken, but the bandwidth
of data traffic on the major ring may suffer for a short period of time
due to this flooding behavior.
