This Cisco-based network is configured with PVST+.The Cisco network of an Example Corp.shown in exhibit is configured with PVST+. What will happen if you change Spanning Tree mode to MST on C3750_1?
The correct answer is 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 10.0015.28b8.f000" and uplink ports are blocked. See the full explanation below for the reasoning.
Question
This Cisco-based network is configured with PVST+.The Cisco network of an Example Corp.shown in exhibit is configured with PVST+. What will happen if you change Spanning Tree mode to MST on C3750_1?
Options
- AOn C3750_1, the root port for Common Spanning Tree will be the port leading to C6509_1.
- BC3750_1 passes all the BPDU sent by C6509_1 and C6509_2, and there is no change in topology.
- CWhen C3750_1 realizes its neighbors are not MSTP compatible, it stops sending BPDUs.
- DC3750_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 10.0015.28b8.f000" and uplink ports are blocked.
