Rb260GS Help

Im trying to configure an RB260GS with one vlan.

I need all the Layer 2 MTU I can spare so I just want to add a VLAN ID=10 on the router board 493, then send that traffic to the switch port 2, and when the switch sees the ID=10, sent it out port 4, strip the vlan header. reverse the process for incoming traffic on port 4.

If I send untagged traffic from the router board to port 2, I just want it to switch it as normal to the other ports, but It seems I have to create a vlan ID of 1 on the router board and the switch and use that? That adds the vlan header and I can’t spare the MTU bytes.

How should I set it up?

RB260GS allows untagged traffic on VLAN trunk port unlike RB250GS.
On RouterBoard VLAN 1 interface is not necessary, but in SwOS VLAN 1 is still needed.
This only works using “VLANs” table! In RB260GS “VLANs” add VLAN ID 1 with “leave as is” on all ports and add VLAN ID 10 with “add if missing” on port2 and with “always strip” on port4.
