SWITCH E
Fig 22-4 MRPP Scenario 3
In above topology figure, SWITCH B, E, D belongs to two MRPP ring 4000 and 100
separately. SWITCH B and D have one port belonging to two MRPP rings, and SWITCH
E has two ports which belongs to two MRPP rings. Under this configuration, if a switch
port belongs to more than two rings, the type of MRPP ring of the port must be transfer
node.
In the above configuration, SWITCH B, E, D has some port belonging to more than
two rings. The special port changing takes a effect on more than two rings, sometimes
one ring changing can affect another one, so that makes confusion. Thus, you’d better
not configure like this, if not must.
