After the primary node occur ring fail, if the secondary port receives Hello packet s
ending from primary node, the ring has been restored, at the same time the primary n
ode block its secondary port, and sends its neighbor LINK-UP-Flush-FDB packet.
After MRPP ring port refresh UP on transfer node, the primary node maybe find ri
ng restore after a while. For the normal data VLAN, the network maybe forms a tempo
rary ring and creates broadcast storm. To avoid temporary ring, transfer node finds it t
o connect to ring network port to refresh UP, immediately block temporarily (only permit
control VLAN packet pass), after only receiving LINK-UP-FLUSH-FDB packet from prim
ary node, and releases the port block state.
