Good afternoon,
I have a Cisco 887VA which I'm trying to configure as a modem only. I've been following a few threads on here regarding the VDSL config for bridged mode which seems to be what I'm after.
The modem side of the router seems to be working correctly as when I type "sh controller vdsl 0" I get the following output, which I've cropped down a little:
Modem Status: TC Sync (Showtime!)
DSL Config Mode: VDSL2
Trained Mode: G.993.2 (VDSL2) Profile 17a
TC Mode: PTM
Selftest Result: 0x00
DELT configuration: disabled
DELT state: not running
Trellis: ON ON

Signal Attenuation: 0.0 dB 0.0 dB
Noise Margin: 4.5 dB 6.0 dB
Attainable Rate: 30632 kbits/s 6304 kbits/s
Actual Power: 11.0 dBm 6.3 dBm
Per Band Status: D1 D2 D3 U0 U1 U2 U3
Line Attenuation(dB): 21.4 60.4 0.1 9.2 49.8 N/A N/A
Signal Attenuation(dB): 21.4 60.4 N/A 9.2 49.2 N/A N/A
Noise Margin(dB): 4.4 4.6 N/A 6.0 6.0 N/A N/A
However, the router (Draytek 3900) which I have connected to the 887VA is failing it's PPoE connection with an error "Message [ PPPoE : No response from server side. ]". I have also tried using a Windows PPoE connection and it fails with "Error 651".
I'm suspicious that my interface config on the Ethernet is incorrect, I'm new with Cisco devices so it's entirely possible I've done something stupid. The BT infinity instructions for VDSL are just to use a VLAN tag of 101 at the modem so I've attempted to modify other bridged configs on this forum to do exactly that.
Here is my current router config:

I have tried using both Ethernet port 0 and port 1 to connect to the WAN port on my Dratytek and also with my PPoE connection on the PC but both behave the same and fail to connect.
Thanks for reading, hopefully someone can spot the error of my ways!
