Hello,
I am trying to setup a vlan on a bridge and am not able to find a viable way to do this.
I have a bridge with 3 interfaces, these ports are connected as uplinks to a virtualization cluster. This bridge is in place to provide a common gateway and access to a single public /24 prefix (the .1 IP of the prefix is attached to the bridge interface and the VMs use that as gateway) to VMs across all 3 nodes. The reason for this setup is I want to be able to migrate VMs across nodes without downtime.
Everything is working as expected.
However, I now want to be able to setup a vlan for a customer who will be deploying multiple VMs and want to setup a vlan for this customer solely for the purpose of bandwidth accounting.
I want to be able to send a vlan over the bridge (effectively sending the vlan to all physical interfaces inside the bridge, this is important since new nodes are to be added to this bridge in the future and I want the vlan to be available on all nodes in this cluster)
BUT, I also want the vlan to be a part of the bridge itself since as I mentioned before all VMs use the .1 IP as gateway.
I also do not want to interrupt the untagged traffic that is currently on the bridge, and want to keep the current traffic untagged, just have an additional vlan passed to all interfaces in the bridge.
What are my options?
Any help is greatly appreciated!
