I've got a Cisco 860VAE-W which I'm trying to bridge. I picked it up because I was interested in learning a bit about an IOS device – I'm coming at this pretty raw.

I'm hooking it up to the Australian NBN (Superloop FTTN) on a rickety bit of wire, but the VDSL2 seems to connect ok.

I updated IOS to

I took a likely looking setup from whirlpool.net and the IPoE twist in that thread and have been hammering away at it since for my

It seems to me that
Ethernet0 is the virtual interface that the DSL modem uses, so that and
vlan1 have been added to
bridge-group 1. Nothing on that bridge gets an IP address (makes sense) and then
bridge 1 protocol ieee seems the right choice. I don't really understand how GE0 finds its way into the bridging setup but I guess it works for other people. Lastly GE1 is configured with an IP address so the device can still be monitored and managed over the network.
So from my nascent understanding, this config looks pretty reasonable and the DSL side appears to be working. But, of course, I can't get the Orbi sitting behind the Cisco to successfully acquire a DHCP lease.
I've been sifting through the Cisco docs; they're comprehensive, but maybe too comprehensive? It feels like finding a needle in a haystack.
So, yeah, how do I bridge a Cisco 860VAE-W from VDSL to Ethernet?
