Sonic.net IPv6 6rd rolls out.

Yesterday, Dane Jasper posted a notice in the Sonic.net forum that their 6rd service has begun:

»forums.sonic.net/viewtop ··· 3&t=1877

They have not updated the Pace 4111N firmware, but third party CPE is supposed to work.

I have played with IPv6 in my Asus RT-AC66U a bit, but am disappointed. It looks like I need to learn the OS CLI in that model. It is supposed to be capable of 6in4 and 6rd tunneling, but can't create the tunnels with Sonic.net data; works fine with Hurricane Electric 6in4, though. Using the HE data, the RT-AC66U shows the following:
          IPv6 Connection Type: Tunnel 6in4
              WAN IPv6 Address: 2001:470:1f04:448::2/64
              WAN IPv6 Gateway: ::
              LAN IPv6 Address: 2001:470:1f05:448::1/64
   LAN IPv6 Link-Local Address: fe80::62a4:4cff:fedc:9198/64
               LAN IPv6 Prefix: 2001:470:1f05:448::/64
                   DNS Address: 2001:470:20::2 2001:4860:4860::8888 2001:4860:4860::8844

The corresponding IPv6 routing table looks, in part, like this:
IPv6 routing table

2001:470:1f05:448::/64                      ::                                      U     256    0        0 br0     
2001:4860:4860::8888/128                    2001:4860:4860::8888                    UC    0      2        0 v6in4   
 

HE gives the border server and client edge server IPv6 addresses as:

2001:470:1f04:448::1/127

For the RT-AC66U, I entered 2001:470:1f04:448::2 in the "Client IPv6 Address" field, and "64" in the "IPv6 Prefix Length" field.

For the Sonic.net 6in4 tunnel, the border server and client edge server IPv6 addresses are:

2001:5a8:0:1::149e/127

I can enter 2001:5a8:0:1::149f in the "Client IPv6 Address" field, but am limited, by the router GUI, to "IPv6 Prefix Length" field values of from 3 to 64; any value outside of that range throws an error. But an "IPv6 Prefix Length" field value of 64 yields the following:
          IPv6 Connection Type: Tunnel 6in4
              WAN IPv6 Address: 2001:5a8:0:1::149f/64
              WAN IPv6 Gateway: ::

               LAN IPv6 Prefix: 2001:5a8:4:a4f0::/60
                   DNS Address: 2001:470:20::2 2001:4860:4860::8888 2001:4860:4860::8844

... with this IPv6 routing table:

It appears that I need to learn how to access the RT-AC66U CLI so I can modify the server/client data to reflect the 2001:5a8:0:1::149e/127.

For the Sonic.net 6rd tunnel I used the data from Dane's post, thus:

Asus 6rd configuration.


But the IPv6 LAN settings don't look right. I changed the "IPv4 Router Mask Length" field value to, "0"; which gives a "LAN Prefix Length" of "60". But still have some problems with a working tunnel:
          IPv6 Connection Type: Tunnel 6rd
              WAN IPv6 Address: 2602:24a:de40:7d90::/52

With this routing table:

2602:240::/28                               ::                                      U     256    0        0 6rd     
 

Since I can get the HE tunnel to work, I suspect some kind of configuration limitation with the Asus RT-AC66U Firmware Version:3.0.0.4.374_2239, which is the (as of this evening) latest, non-Beta release.

Works fine for me on my RT-N66U with Asus firmware, but it with a :32 prefix length instead of :28. Seems like they're still working things out from reading that thread.

Welp, looks like they worked it out and the :28 prefix is working.
