Is it possible to create an IP unnumbered setup with PPPoE on OpenBSD?
And what the heck you mean by "unnumbered"? If it is wildcard address,
and by it, that the pppoe access concentrator provides the ip addres,
then yes, it works. For us to help you we need a little more than this.
Sorry for not providing enough information. "IP unnumbered" seems to mean
that both the pppoe physical device and the pppoe device don't have an
IP-address. Only the internal interface has an IP-address. The following
is a Cisco configuration that shows such a configuration.
interface FastEthernet0/0

My setup is exactly like this. The physical interface do not have an ip
address and the pppoe also do not have an ip address until the
concentrator provides one:
inet 0.0.0.0 255.255.255.255 NONE \
pppoedev <physical_dev> authproto pap \
authname 'user' authkey 'pass' up
dest 0.0.0.1
!/sbin/route add default -ifp pppoe0 0.0.0.1
The point behind unnumbered is that the ppp interface *doesn't* have an
IP, usually this is when the WAN address is inside a routed subnet.
Since PPP is layer2, IP addresses aren't actually needed.
