DHCPv6, TunnelBroker problems, need help.

RouterOS General

Hello. I’m trying to make dhcpv6 on my RB493G.
IPv6 with RA configuration works, but DHCPv6 looks like a bit tricky to configure. And no, "just use RA is not an answer :slight_smile:
Here is my config:
IPv6 addresses (link-local skipped)

ADDRESS FROM-POOL INTERFACE ADVERTISE

1 G 2001:470:71a9::/64 internal-bridge noIPv6 ND:
1 interface=internal-bridge ra-interval=3m20s-10m ra-delay=3s mtu=unspecified reachable-time=unspecified retransmit-interval=unspecified ra-lifetime=30m hop-limit=64
advertise-mac-address=yes advertise-dns=yes managed-address-configuration=yes other-configuration=yes…And ND prefix:
0 prefix=2001:470:71a9::/64 interface=internal-bridge on-link=yes autonomous=no valid-lifetime=4w2d preferred-lifetime=1wOh, and ipv6 pool:

NAME PREFIX PREFIX-LENGTH

0 home-ipv6 2001:470:71a9::/64 112DHCP server sitting on bridge. Same net also assigned to bridge as you can see. But trying to get IPv6 ending with this message:

So i switched to /48 and now what i get:

2012.10.07 22:32:12 Client Info      Creating SOLICIT message with 0 IA(s), no TA and 1 PD(s) on eth0/2 interface.

2012.10.07 22:32:14 Client Notice    Insist-mode disabled, giving up (not sending INF-REQUEST).

As i can see, it can delegate prefix. But not IP.

So huh, after some digging… is MT’s implementation of DHCPv6 includes only DHCPv6-PD and not TP/IA?

4

Yes, currently only DHCPv6-PD. It is stated in the manual.

Any ETA on full implementation? Almost all unix dhcpv6 servers already support PD,TA and IA :slight_smile:
