forwarding untagged ethernet traffic via tagged ethernet

Hello Guys,

I have difficulty in transporting untagged traffic over tagged Ethernet interface with Mikrotik, i tried multiple method but nothing worked , I have following scenario any help would be highly appreciated. MK1 and MK2 are client end routers and have only one Ethernet and one wlan port.

Case 1

Client( send tagedVLAN3001)–(VLAN3001)tag-ether1-MK1<----->wlan1<---->Mk2----(VLAN3001)tag-ether1-PE1(VLAN3001) Routers-MPLS Core- PE2

or
Client( utagged)–untagged-ether1-Mk1<----->wlan1<---->Mk2----untagged-ether1-PE Routers-MPLS Core- PE2


Case 1 works fine ,interface vlan3001 does not have any IP and I m using VPLS to tunnel traffic till PE router and from PE router haves another VPLS to transport the traffic till end node. One VPLS between Mk1 and Mk2 and the other VPLS between PE1 to PE2. But in this case I can not manage the Mk1 or Mk2. I need help for following case 2.

Case2

Client( send untagged traffic )<–>(VLAN3001)tag-ether1-mk1<----->wlan1<---->Mk2----(VLAN3001+VLAN3002withIP)tag-ether1<----->PE1( VLAN 3001+VLAN3002withIP) Routers-MPLS Core<------>PE2

Interface vlan3001 does not have any IP on both side but interface vlan3002 which is on MK2 router does have IP for management purpose- and interface vlan3002 works fine – can manage the routers but now no client traffic :slight_smile:

I tried to transport untagged traffic via different methods like , created a bridge1 and attached to ether1 and then created a vlan 3001 assigned bridge1 as interface to it , then created another bridge2 attached vlan3001 and vpls interface to it; on MK1 router but it does not work. I used same setup in case with eoip on clinet routers but nothing worked.

Any help would be highly appreciated. Thanks in advance.

If you want to add/change vlan tags then you need managed switch. Or if you are using routerboard then you can use built in switch chip features.

I need this funktion on the Routerboard 411 and Routerboard 711

if mac ist 11:11:11:11:11 then change vlanid to 33

You won’t be able to do that with a MikroTik. It is a router, not a switch, it does not support changing VLAN tags. It handles VLANs like Linux does, each VLAN is an interface unto itself, so you won’t be able to change what interface the traffic came in on.

bridge action or firewall

it is posible

The screen shot you have there is part of the Switch Chip, NOT part of the firewall or the bridge.

The 411 and 711 do not have a switch chip built in. The RouterOS is a router operating system, not a switch operating system.
