Double Q tagging

RouterOS General
1

Is is possible to have a double Q tagging?

Like :

                                +--------------+      vlan 10, 12
                 ---------------|     MT       |------------
   vlan 2215 with               +--------------+
vlan 10, 12 inside

And if it’s possible how do I do that?


thx in advance

As in Q-in-Q tagging / VLAN-Tunneling (cisco)?

If so, I dont think it is possible, mainly because on a RB you cant set the MTU higher than 1502. For Q-in-Q tagging to work properly you need minimum of 1500+2+2. ie. 1500 for the ethernet frame, 2 for the VLAN tunnel, and 2 for the internal VLAN.

The particular feature is implemented in RouterOS3.0
It will work ony with suitable interfaces with Q-in-Q driver support.

Do the routerboard 532 have these drivers?
