VLAN over PPPoE possible ?

First of all I want to make clear that I am speaking of VLAN over PPPoE, not VLAN to be used for PPPoE, i.e. I am speaking here of VLANs once the PPPoE/PPP connection is up and running. So I do not attempt to open several PPPoE connections over separate VLANs, but use one single PPPoE which encapsulates several VLANs

I do have the PPPoE server connected to ether1 and configured pppoe-internet interface for pppoe. In the following I speak about packets comming in from the ISP (or out to the ISP) through the pppoe-internet interface.

My ISP offers different services internet, voip and ipTV with each having its own VLAN. Currently I have not been able to setup VLAN on the MikroTik router (RB3011) for the ppoe-internet interface thus using the default VLAN which makes the internet work at least.

All attempts to separate the VLANs from the PPPoE interface failed so far. I.e. creating a VLAN interface fails because the pppoe-internet is not selectable as Interface for a VLAN interface. The second idea was to separate the VLAN in a bridge by creating VLAN interfaces for the bridge but this fails as I cannot connect pppoe-internet interface to a bridge.

You can connect the pppoe into the bridge by using the ppp profile

Great, thanks for the pointer. I was not at all looking at the PPP profile.

I have copied the default profile used and added the bridge to the copy. Then I have updated the PPP interface to use the new profile. Then I restarted the ppp interface but I see no trafic on the bridge. Hope this is normal (no VLAN interfaces yet added), usually the bridge shows traffic when a port is assigned.

I also have trouble getting an IPv6 prefix from my ISP (dhcp client refuses to start), thought the PPP profle settings regarding IPv6 might help as I did not look for those either before, but unfortunately no advance at that end neither.
