I have a SDSL access, and my ISP ask me to set a pppoe session over the vlan2900, with the priority code 2.
Before I was working with Zyxel, and I just had to specify priority code in vlan settings.
Now I work with Mikrotik (and I love the freedom they offer), and I don't know how to do that.
I tried a mangle rule :
/ip firewall mangle add action=set-priority chain=output new-priority=2 out-interface=vlan2900 passthrough=yes
I think that's because firewall works on layer 3 when pppoe is layer 2, right ?
So, could anybody explain to me how to do what I want to do (if possible) ?
