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?
