Has anyone figured out how to assign a PPPoE client a static IPv6 /64 pool? I am doing it right now with DHCPv6 PD Pool on the PPPoE profile but I do not seem to be able to insure they get the same /64 each time and that is not very useful.

Hello,

We are testing PPPoE and IPv6 addresses and we use a freeradius server in order to assign prefixes to the client routers. At present time we've achieved the authentication and delegation of prefixes, but the attached DHCPv6 client on the pppoe-out interface isn't working as in this RouterOS Manual example:

http://wiki.mikrotik.com/wiki/Manual:IPv6_PD_over_PPP

We are using the next RADIUS attributes with different results, the red ones are not working well while the green ones do their work:

test User-Password := "testing"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IPv6-Address = 2100:0:1::1,
Framed-IPv6-Prefix = 2100:0:0:4::/62,
Delegated-IPv6-Prefix = 2100:0:1:1::/62,
Mikrotik-Delegated-IPv6-Pool = 2100:0:1:2::/62,
Framed-Routing = Broadcast-Listen,
Framed-Filter-Id = "std.ppp",
Framed-MTU = 1492,
Framed-Compression = Van-Jacobsen-TCP-IP


The pppoe-out interface connects to the server and the next IPv6 routes are established between both Mikrotik routers (RB750 and CCR1016-12G):

• 1.- RB750 has IPv6 default route: ::/0 pointing to pppoe-out interface and is reachable
  2.- CCR1016-12G has a route pointing the Framed-IPv6-Prefix address 2100:0:0:4::/62 to the pppoe-out interface
  3.- CCR1016-12G has a route pointing the Mikrotik-Delegated-IPv6-Prefix 2100:0:1:1::/62 to the Link Local Address of pppoe-out interface

But the DHCPv6 Client doesn't obtain an IPv6 address from Framed-IPv6-Address for the WAN interface, nor sets a DHCPv6 Server in the LAN interface with Mikrotink-Delegated-IPv6-Pool. If you achieve this part, we will very pleased to see your comments here.


About Delegated-IPv6-Prefix, it is in the features list requested for ROSv7 and I don't know yet why Framed-IPv6-Address is not working in our lab, but this last isn't relevant.

You can configure your Mikrotik NAS as a RADIUS Client following the RouterOS Manual:

Delegated-IPv6-Prefix = 2100:0:1:1::/62,
Mikrotik-Delegated-IPv6-Pool = 2100:0:1:2::/62,

I don't know if this was simply an oversight while throwing together some samples for your post, but the /62 prefixes in your example aren't on /62 bit boundaries.

Valid /62 prefixes would be:
2100:0:1:0::/62
2100:0:1:4::/62
2100:0:1:8::/62
2100:0:1:c::/62
2100:0:1:10::/62
2100:0:1:14::/62
etc...
