Openwrt configuration for connection to VDSL router in bridge mode

Good evening, if I ask my ISP to set their VDSL router in bridge mode, how should I configure my own router? I've seen many examples, but I'm afraid they were meant for dsl routers with installed openwrt.

Routers will be connected via ethernet. I think I need to do authentication on my router. Any working example for similiar VDSL connection? Provider is Telekom in Slovakia.

Here's info from their site for ADSL

aDSL connection
VCI 32
Protocol PPPoE
Encapsulation LLC alebo LLC/SNAP
Modulation ADSL2+ Multimode
Modulation ADSL G.DMT or ITU
Service category UBR
Band width Annex B
MTU 1492
VLAN ID for VDSL 2510

I guess the only parameter I need from the table for VDSL is VLAN ID?

Apart from configuration, do I need to install any packages?

Thank you.

EDIT: "I think I need to do authentication on my router" - I'm actually not sure whether this is true, because on other LTE router I have with bridged lte modem, all configuration is done on that LTE router. Any ideas?

See for examples (and the guide at is also always worth keeping in mind). The stanzas not referring dsl0, but eth0 (or wan on DSA based configurations) generally apply to your case, e.g. (tagging with VID 7 in this case):

config interface 'wan'
        option proto 'pppoe'
        option ipv6 '1'
        option device 'eth0.7'
        option username ''
        option password 'pass'

Hello, thanks for info. I don't want to use IPv6, other than that I had idea what to use. I thought if anything else is needed like from

config dsl 'dsl'
        option annex 'b'
        option ds_snr_offset '0'
        option firmware '/lib/modules/vr9-B-dsl.bin'
        option line_mode 'vdsl'
        option tone 'av'  

Or are these options to be configured on openwrt routers having dsl modem inside only?

On the current ISP router with dsl modem, I could see these:

Transmission mode VDSL2-17A Annex B
SNR (Down/Up) 12.8 / 26.0 dB
Attenuation (Down/Up) 13.0 / 17.5 dB


That stanza only applies to lantiq devices with an integrated modem. Using external modems, those settings need to be done there, on the modem (using their management interface) - OpenWrt doesn't know about those, unless it's the modem itself.

Alright, so basically what I need to do it authentication and VLAN, is that correct?

Thanks @slh

Yes, what I've pasted above.
