Hi guys, the plan is to use a DrayTek v130 in bridge mode for the VDSL service, with a MikroTik RB951G-2HnD behind it providing the firewall/pppoe dialer etc.

Unfortunately the Mikrotik can't connect.

The DrayTek when acting as a the PPPOE dialer connects successfully, so it's not the VDSL connection itself.

The configuration of the DrayTek (192.168.0.254) is as follows (taken from the guides I found online)

With the Mikrotik config (in its default 192.168.88.1 config for the moment is) as follows:

The firewall rules (not pictured) will move from the default connection to the PPPOE connection.

Does this look correct? Another guide referenced using just the PPPOE pass-through feature and disabling MPoA.

This is the first time I've had to deal with VDSL and a MikroTik. I've only used them on fibre connections.

Hi, you should not need vlan10, just connect the pppoe direct to the 130. The reason is that the 130 is connecting on vlan10 and providing you with the pppoe circuit untagged.

Double tagging? No need in tagging on Mikrotik if you do it on DrayTek

Well spotted guys, and thanks for the quick reply.

The original config I did just had the VLAN 10 on the DrayTek which seemed logical to me, however a colleague said I should have that only the MikroTik as well which seemed a bit odd, but hey it was worth a try.

The original VLAN-on-DrayTek config also didn't work, so there must be something else going on as well.

vlan tag should be set in the customer column rather than service column. Mikrotik is PPPoE on ether1.

Jump on Snappernet's website. They have the Draytek bridging configs sitting there ready to go.

One mistake in my reply: The original VLAN-on-DrayTek config did work, without the bridging enabled.

If you set VLAN10 on the DV130 in Bridge mode then it strips it on the way out

If you have not set VLAN10 on the DV130 then it passes it through for Router to sort.

And as above use 'Customer' not 'Service'
Tutorial here:
https://www.draytek.com/en/faq/faq-connectivity/connectivity.wan/how-to-use-pppoe-pass-through-and-bridge-mode-on-vigor130/

I normally set the DV130 with VLAN10 one less thing to worry about on the Router in my case a ERL3

Good practice is to let the tag pass and to handle it in the router. This is mandatory for IPTV (i.e. HDTV, or other) services to be sorted out at router level as well you otherwise can't do anymore when stripped before at modem level. Furthermore, when you upgrade to an ONT, I'm not sure you'll have access to the ISP equipment's config and therefore you have to handle it in the router at latest.

- SRV: 12 RU HA server cluster, 0.1 PB storage on premise
- IoT: thread, zigbee, tasmota, BidCoS, LoRa, WX suite, IR
- 3D: two 3D printers, 3D scanner, CNC router, laser cutter

The last two examples in the guide are the relevant ones and use 1483 Bridged IPC for the encapsulation, and that's what an example script from Snappernet I was sent uses.

However that contradicts another guide I found from SnapperNet that uses Bridged IPoE for a Chorus VDSL connection:

http://downloads.snappernet.co.nz/draytek/dv130/Draytek%20DV130%20Chorus%20VDSL%20Bridged%20Sample%20Configuration.pdf

So which is the correct one?

Once it's all working I'll move the VLAN tagging to the router.

I refer to your first picture above:

1) Set DSL mode to VDSL 2, not to auto (fixed).

2) Disable VDSL2 tag value 10 in the service section.

3) Set it to 10 and enable it (for the moment) in the customer section - leave the priorities alone. Save.

When you'll handle it later in the router, disable all tagging here in the DT130.

2nd picture:

4) Disable PPPoE/PPPoA client mode, that's all for that page. Save.

3rd picture:

5) Enable MPoA / static or dynamic IP, the VPI, VCI, channel and encapsulation settings should be ok for your country - I don't know yours, I have different numbers.

6) MTU for PPPoE is 1492 at this point, set or let it at this value.

7) Bridge Mode: IMPORTANT to ENABLE! Save.

8) If an DHCP server appears on the right side, you could disable it since it's not needed in Bridge Mode.

Don't forget to change the default admin password!

You could do some additional settings like Date/Time, Modem's name, ... Since I use an other or later f/w version, there is no picture of the IP settings of the modem (mostly 192.168.1.1). I'd recommend to set/let it to something like 192.168.x.1 and the microtik to 192.168.x.2 (for example). You can adapt to one of the both party's default IP address range (this will have later on the benefit to set a route in the DT130 thus to be able to reach it from your home network as admin or request the status of the modem).

Having this configured, the successful connection will be a question of the mikrotik configuration now I'm not familiar with - sorry for that.

Good luck!

There are three different scenarios of setups for ADSL and VDSL bridging in NZ and then the option to tag in the router or modem on two of them which gives five different types of setups - there isn't a one solution is correct or best other than option 1 being the least best option, and (off the top of my head) also limiting you to a max MTU of 1492 for PPP whereas the others can support 1500 PPPoE if your RSP supports it.

1 - Bridging on ADSL or ADSL2+ doing PPPoA to PPPoE conversion

2 - Bridging on ADSL2+ using native EUBA passthru for IPoE or PPPoE using 0/110 and VLAN10 tagging on the modem (if your RSP supports this as it's delivered on a different CVID and SVID to option 1)

3 - Bridging on ADSL2+ using native EUBA passthru for IPoE or PPPoE using 0/110 and VLAN10 tagging on the router (if your RSP supports this as it's delivered on a different CVID and SVID to option 1)

4 - Bridging on VDSL2+ using native EUBA passthru for IPoE or PPPoE and VLAN10 tagging on the modem

5 - Bridging on VDSL2+ using native EUBA passthru for IPoE or PPPoE and VLAN10 tagging on the router

Whether good practise or not here is what I have and it works on my DV130 running 3.8.3 Modem8 firmware)

VLAN10 set and stripped

Just tick 'Bridge mode'

Thats all I need for VDSL
I change the default IP to a different Subnet as my modem is behind a PtP link so its accessible by ERL3
Everything else I leave as default

If you want the router to do the VLAN10 leave it disabled and the DV130 passes it through (tested as well with ERL3)

Since he mentioned VDSL before, there is only option 4 or 5 and that's covered by my posting. So, no need to discuss options 1 ~ 3.

The only uncertain thing left might be an 1492+8 MTU size mentioned WHEN supported by the ISP. Your configs aren't too far from those faded away in other countries. ;-)

Interesting topic because I noticed that my DV130 config is similar (including my MTU set to 1500) however my VPI is 0 and VCI is 110 and it has been operating this way for many years with no adverse effects (that I am aware of).

Should I be running VPI 8 and VCI 88 ?

(I think the 1500 MTU and VPI 0, VCI 110 were recommended by a Spark/Telecom VDSL2 document)

Hi, the VPI and VCI are ADSL related, not VDSL, so will not matter
