When the edge port receives STP BPDUs, the value of Active is changed to disabled and the port becomes a common STP port. The following log information is recorded: MSTP/4/EDGE_PORT:Edged-port [port-name] received BPDU packet, then the active state of the edged-port will be disabled!
which includes the BPDUs, undergoes deferment or collision and eventually gets dropped. From an STP point of view, because bridge B does not receive BPDUs from A any more, bridge B has lost the root bridge. This leads B to unblock the port connected to bridge C, which creates the loop...

In this instance it uses the BID and Port ID. MAC address and Priority are used in the election of the root bridge. 4 Helpful Reply Jose Manuel Garcia Level 1 In response to chris noon 02-19-2017 11:04 PM Thank you, chris, So, root ports are always elected according to ...
