Hahah. Yup. It worked on ethernet only because I did it correctly on
ethernet. I had address selected rather than prefix on the client on
PPPoE interface.
Thanks,

What version of RouterOS? On your DHCPv6 Client on the client 'tik,
did you tell it to request an address or a prefix? (You want prefix).
Like the attached. Then in IPv6-Addresses, you'd add one like the
other attached pic.
FWIW, I don't know that a Mikrotik will actually install a global v6
address right on the PPPoE client interface because strictly speaking,
one isn't actually needed. IPv6 Routing is always done using the
link-local/interface anyway (that is, the default gateway is either an
interface (point-to-point) or the link-local address and interface
combo of the upstream router. If the Mikrotik needed to send an IPv6
packet out to the Internet for some reason (maybe a DNS query for a
proxied client), it will use any local global address and send it out
with that as the source IP. It doesn't have to be the "WAN" interface
for it to work.

Inside PPPoE it's not working. I see the dynamically created v6
server, but the client sits there "searching".
.....I'll have to figure out these unintuitive gotchyas you mentioned.

Yes. In your PPPoE profile, you'd specify a v6 Prefix Pool for both
the "Remote IPv6 Prefix Pool" and the "DHCPv6 PD Pool" (it can be
from the same pool, it will assign them two prefixes from that
pool). The former is for the WAN port of the customer's device and
the latter is for the delegated prefix that goes on the LAN (and is
what creates the dynamic DHCPv6 instance) - most consumer routers
that support v6 need both the address for it's WAN interface and the
PD prefix for the LAN before they'll route IPv6.
Need to allow DHCPv6 in the Input of the IPv6 firewall (if you're
otherwise blocking most other input).
If you want to also provide both IPv4 and IPv6 DNS servers to your
dual-stacked PPPoE subs, you need to add IPv6 DNS servers to the
Mikrotik in IP-DNS along side whatever v4 DNS servers you have on
there. It will use those to pass along to the PPPoE subs
(unfortunately, can't just specify the v6 DNS servers in the PPPoE
profile like you can the v4 DNS servers.
If you have a series of input firewall rules for IPv4 to protect the
router, you'll want to duplicate those in IPv6.

I was playing with an example from the Wiki. Looks like it
dynamically creates a dhcp6 server instance on the server end of
the PPPoE tunnel and makes a prefix delegation to the client. The
example didn't include ipv4, but I assume that v4 address gets
assigned by PPP as normal. Is that the gist?

I've chosen to have PPPoE servers at each tower because I'm routed
and already have a router there, but centralized or routed,
doesn't matter - pros and cons to both.
I also have dual-stack v4/v6 in production on PPPoE with Mikrotik
as concentrators - works great. Few gotchas that aren't intuitive,
but nothing crazy.

Depends on your network and its exit points.
Yes you can have dual or quad PPPoE Servers.
Nope you can run PPPoE in a VLAN
Yes you can simply dual-stack with PPPoE, it’s the simplest method to do so.
At the same time no problem.

Subject: [AFMUG] PPPoE
I haven't done much with PPPoE.
For those of you who have, do you generally try to carry L2 back to one central
PPPoE server? Or do you sprinkle PPPoE servers around at each tower?
Can you have redundant PPPoE servers somehow?
Is there any reason I can't carry PPPoE inside a VLAN?
Can you run dual stack with PPPoE? It looks like a Mikrotik PPPoE server can
assign v6 addresses, but I'm wondering if it can do both v4 and v6 at the same
time.
Anything else a newb should do or not do?
