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.

I have two 'tiks connected with an ethernet cable. A DHCP6 server

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?
