We have an NE05SQ router.The router has a QinQ sub-interface which is bound to a VSI. We want to transparently transmit BPDU packets over the VPLS instance, however the commands are not supported on sub-interfaces. Is there any alternative that we can use to transparently forward BPDU packets?

Hello!

Since the QinQ sub-interface can’t support the command link-protocol transport bpdu, I propose 2 solutions:

1. I don’t know what BPDU you want to transparently forward, if only STP BPDU is tagged, you can configure link-protocol forwarding on the main interface. But if BPDU is untagged, this solution wouldn’t work;

2. swtich to another type of sub-interface, such as the VLAN-type dot1q sub-interface, on which you can configure link-protocol transport bpdu. This solution can be effective for both tagged and untagged BPDUs.
