IPv6 6RD testing

We haven't yet rolled this out to our own Pace 4111N CPE, but it is coming soon. When that occurs, all members using that equipment will automatically see full native client IPv6 automatically.
Meanwhile, members with their own CPE who have asked for IPv6/6RD capabilities can now give it a try. Here are the settings:
6RD prefix: 2602:240::/28
6RD Endpoint: 184.23.144.1
Let us know here if you have success getting IPv6 working, but please don't contact technical support about IPv6, it's experimental and unsupported. Thanks!

So far, not working with my Asus RT-AC66U. The 6rd fields are:
Code: Select all
IPv6 Prefix:
IPv6 Prefix Length:
IPv4 Border Router:
Entering your posted values of:
Code: Select all
IPv6 Prefix: 2602:240::
IPv6 Prefix Length: 28
IPv4 Border Router: 184.23.144.1
Does not seem to create the tunnel. I get an IP address, but no Internet access:
Code: Select all
Tracing route to www.google.com [2607:f8b0:4005:800::1012]
over a maximum of 30 hops:
1 3 ms <1 ms <1 ms 2602:24d:9000::1

And
http://test-ipv6.com/ fails 0/10.
When I go back to my Hurricane Electric 6in4 tunnel I pass 10/10, and traverse the IPv6 Internet:
Code: Select all
Tracing route to www.google.com [2607:f8b0:4005:800::1012]

Trace complete.
I can't even get the Sonic.net tunnel working, I believe due to a bug in the RT-AC66U GUI, which limits the prefix length to two digits, where I need to use three: 2001:5a8:0:1::149f/127 (the field maxes at 99).

Our initial test environment was configured for a 6RD prefix of 2602:240::/32, and changing the prefix lenght for production was overlooked. I have updated our configuration to use 2602:240::/28, so please give your same configuration another try and report back!
----
For anyone who would like to try manual tunnel configuration on a unix box, the following steps should be useful.
Example IPv4 Address: 50.0.228.2
A useful tool for converting your IPv4 address into a usable 6RD address is available at
http://silmor.de/ipaddrcalc.html under the ' IPv4 to IPv6 Transitional' section
Convertion tool information:
Provider prefix IPv6: 2602:240::/28
Customer IPv4: 50.0.228.2/32 (replace with your IPv4 address)
* Click 'ISP -> Customer' and use an IP from the resulting "IPv6 Customer prefix"
Example output: 2602:243:200E:4020::/60
ip addr add 2602:243:200E:4020::1/60 dev eth0
ip tunnel add 6rd mode sit local 50.0.228.2 ttl 64
ip tunnel 6rd dev 6rd 6rd-prefix 2602:240::/28
ip addr add 2602:243:200E:4020::1/60 dev 6rd
ip link set 6rd up
ip route add ::/0 via ::184.23.144.1 dev 6rd

The above needs to be configured for 184.23.144.1 as you had previously.

Looks like some sort of BGP issue on Google's side, with your not being able to enter their backbone. Try tracing other IPv6 sites to see if it is really Sonic's problem.

Actually, in fact, it does seem to be a BGP issue on Sonic's part. I can't traceroute into its IPv6 network either. I'm guessing Sonic is going to be bringing up more BGP sessions though (including both peering and transit; remember that every tier 1 network has to be able to see Sonic's routes).

After a "duh-oh" moment (I was switching between HE 6in4, Sonic.net 6in4, and Sonic.net 6rd), somebody straightened me out about the appropriate IPv4 address for the 6rd tunnel. Properly configured in my Asus RT-AC66U, my trace route looks like yours:

I hope Sonic.net gets things sorted out, soon.

My Asus RT-AC66U has a field labeled, "IPv4 Router Mask Length" right below the field for the 6rd endpoint. The router defaults to a value of, "24". When that failed, I poked around the Internet, and came across a web page for configuring a Comcast 6rd tunnel. The instructions were to use a value of, "0", in that field. When I changed from "24" to "0", I could finally get something going; but I am still failing at
