Hi there, Im trying to make my PPPoE concentrator to work over a VLAN. Right now its directly on the interface but since Im starting to sell dedicated links its interesting to get all my PPPoE clientes on a VLAN and not directly on the ether interface because I wanna QoS and shape the bandwidth of my total link so the Dedicated clients will get their band and the clients wont take a share. My first try was to set a VLAN and set the PPPoE server interface to that VLAN but the result was no one connecting anymore, so I addes the same VLAN on the RBs connecting the clients to see if this would solve the problem but it didnt. Any suggestions on how can I make it work? One more question, do I need to set any routes or IPs on the VLAN that will get the PPPoE connections since the PPPoE will dynamicalli set the IPs on the pool?

That is the correct approach. If it didn’t work you implemented it wrong. If you want help with that you’ll have to share the configuration you tried.

No. VLANs are just like any other interface. The PPPoE clients will still be directly connected to the router, just as if only physical interfaces were involved.
hi there, Im showing the config Im using!
0 R WAN-20MB ether 1500
1 R InterServers ether 1500
2 R APs ether 1500 1600 1600
3 R LAN ether 1500 1600 1600
4 R RB-Wi vlan 1500 1596
5 R Clientes Wireless vlan 1500 1596
The Clientes Wireless is the interface I want to place PPPoE concentrator over. It dont have any IP designated on it.
I placed the same VLAN on the RBs that get the clients connections on my towers. But as soon as I get the PPPoE from the APs to Clientes Wireless the PPPoE stop working. I will place my radius config also:
0 ;;; FreeRadius2 CentOS
ppp 192.168.1.109
login
hotspot
VLan Config:
NAME MTU ARP VLAN-ID INTERFACE
0 R RB-Wi 1500 enabled 3xx APs
1 R Clientes Wireless 1500 enabled 2xx APs
Any advice?
Hi again, just passing by to see if anyone has a solution. I will try some options like virtualizing ROS and creating Virtual interfaces on the VM to act as the VLANS but without ID, the problem is that everytime I add a new interface I need to restart the VM to make the System recognize it. PPPoE over VLAN should work fine but I cant see what Im doing wrong.
Your approach is right - add the PPPoE server to the VLAN, but you need to ensure that the packets are arriving into your PPPOE server already tagged into the right VLAN otherwise they will not get delivered to the VLAN interface (and thus not see your PPPOE server which is bound to that interface). Either you should tag them at source and bridge all the way through, or tag them at the layer 3 device immediately prior to your PPPOE server.
I have this same setup working as you describe… I have PPPOE tunnels for VOIP and different PPPOE tunnels for Internet such that I can apply QOS through the network.

Thx Rich, this make me feel more confortable since I know this setup is working for someone, Now I will just try some setups on the routers that are bridged since the problem probably is about tagging packets to the right VLAN so the PPPoE concentrator receives them!
Cya.
I was hoping to get an answer on the question since am trying to
Have a customer VLAN at the core router and carry it to a tower
and tag the interface where the AP is connected. That way the
I run a PPPoE concentrator on the VLAN at the core router.
Problem is PPPoE clients cannot connect but if I do a PPPoE scan
I see the PPPoE server from the core router. I have untagged the
VLAN on the ethernet port the AP connects to.
