odhcpd does not seem to respond to dynamicaly created interfaces such as ppp1 etc..

I'm probably the only person trying to get ipv6 working via pppoe to down stream routers on openwrt.
I can establish an ipv6 local link connection over pppoe but it looks like odcpd isn't responding to requests that come in over these interfaces. I may be doing something wrong, but is this expected behavior and how would I go about enabling it ?
Cheers.

So iI'm probably the only person still trying to get ipv6 working via PPPoE to downstream peers.
Having the same problem. odhcpd does not relay nor advertise on ppp+ interfaces.
It just logs this: Failed to send to fd4f:[my-subnet]::1%downstream@ppp0 (Bad file descriptor)
where "downstream" is the uci interface that uses a physical bridge interface, and ppp0 is brought up by rp-pppoe service.
Edit: Works as expected on an the actual ppp0. Still does not make sense to me why odhcp works on bridged intefaces+VLANs (br-an) but not on bridged pppX devices. That way several ppp+ devices could be joined in one UCI interface.

I also have the same question
