What will happen if you change Spanning Tree mode to MST on C3750_1?

  • A

    On C3750_1, the root port for Common Spanning Tree will be the port leading to C6509_1.

  • B

    C3750_1 passes all the BPDUs sent by C6509_1 and C6509_2, and there is no change in topology.

  • C

    When C3750_1 realizes its neighbors are not MSTP compatible, it stops sending BPDUs.

  • D

    C3750_1 generates a syslog message such as: *Mar 1 06:50:28.960: %SPANTREE-2-
    PVSTSIM_FAIL: Blocking root port Gi1/0/1: Inconsistent inferior PVST BPDU received on VLAN 10, claiming root 10:0015.2b88.fd00" and uplink ports are blocked.
