Hi,
I have one of my customers requested us to enable BPDU packets to send over between their L2 connection and later I have found BPDU filters are enabled.
Therefore, I have deleted the BPDU filter from our (ISP) L2 path but still, they are advising me that they do not receive any BPDUs.
Here with the outcome from our Switch:
