We have a vlan mismatch between our main office and test networks.
The native vlan in the office is vlan1. In the test network their main subnet is vlan1, and the office subnet is vlan3.
I'm trying to link the two networks together and avoid broadcast traffic from the test network. I thought of setting the native vlan for the trunk to vlan3, so office traffic is untagged. How will the office switch then deal with vlan1 tagged traffic coming through the trunk (when the office switch is vlan1 native)?
