Re: [Internet] ipv6 6rd

Thanks Damir for these detailed test results. I will look into all the above and get back to you.

I have a similar setup with the CGN3 and DD-WRT at home so I should be able to replicate most of these tests.

Damir,

I configured a setup similar to yours, same modem, different router but with similar firmware and running DD-WRT.

I replicated the following tests:
1. Speedtest from Comcast (Chicago server)
»stage.results.speedtest. ··· 1284.png
Results are showing IPv6 speed about half of IPv4 so there is an issue there. 6RD does include some overhead but it shouldn't be as bad as this.

2. Traceroute to Google
Hop 2 is missing, that is the 6rd relay. Rest is normal as opposed to your trace
traceroute6 to google.com (2607:f8b0:400b:807::1003) from 2607:f090:XXXX:XXXX:3dda:31a:fd2e:f60d, 64 hops max, 12 byte packets

6 2001:4860:1:1::32c:0:8 12.076 ms 12.214 ms 13.242 ms
7 2001:4860::1:0:713a 11.237 ms 34.506 ms 33.054 ms
8 2001:4860:0:1::4ab 11.598 ms 11.385 ms 11.603 ms

2607:f8b0:8000:26::6 11.390 ms

3. Test »ipv6test.google.com
All good, I'm ready for the future of the Internet!

4. Test »ipv6-test.com
Everything is good except my IPv6 hostname (we don't provide reverse mapping on 6rd IPs)

5. Test »test-ipv6.com
Score 10/10 with a mention that I'm using a 6rd provider

6. Ping googlemail-smtp.l.google.com
davem@Oceania:~ $ ping6 -c 10 googlemail-smtp.l.google.com
PING6(56=40+8+8 bytes) 2607:f090:XXXX:XXXX:3dda:31a:fd2e:f60d --> 2607:f8b0:4001:c07::10

16 bytes from 2607:f8b0:4001:c07::10, icmp_seq=9 hlim=53 time=36.853 ms

10 packets transmitted, 10 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 36.853/44.056/60.683/6.706 ms

So overall, I was able to replicate your speed issue but there seems to be another problem with your setup that I can't replicate. I'll focus first on the speed issue and once this is adressed, I'll look at the other issues.

Thanks for getting back to me again, and thank you for confirming about speed issues.

We are looking into the script, to see if there is a issue on my side for time outs, etc.

Hope you guys will be able to fix speed issue.

Are you able to do the same test with different modem, just to see if its the modem issue (firmware) or something @ Rogers network?

Thanks,
Damir

So, everything else expect speed test is fine on my side now, as well.

Hopefully - you guys will be able to address this issue.

I got 18 out of 20 tiles but frankly, I don't know what the 2 missing tiles are.

Glad you resolve your packet drop issues so now let's focus on the speed issues. I'll run a few more tests on my side and will also see if I can try another modem but that may take a few days for me to source it.

Thanks for providing that info.

Clearly, Router\Firmware is not an issue, so, its either something at rogers or there is a issue on firmware for CGN3.

I'll be moving to a different address in November, I'd imagine my POI right now would be Greensboro but I doubt a different POI Would make a difference. 50/50 toss on greensboro or scarlett.

For those running Rogers IPV6 (6rd).

So far (correct me if i am wrong) Windows 7, 8 and 8.1 are preferring IPV6 over IPV4 if available.

In case, you are having issues described here, (slow speeds) - i would recommend (until its fixed) preferring IPV4 over IPV6, but, still keeping IPV6 working, just in case (at least for troubleshooting purposes for now).

To do this, there are 2 ways, one is editing registry (which didn't work for me in Windows 8.1) or by doing this:

1) run CMD as Administrator, and type this:

C:\Windows\system32>netsh interface ipv6 add prefixpolicy 2607:f090::/32 3 6
Ok.

damir: Windows and Linux will prefer IPv6 over IPv4 when they are available. The exceptions to this are if you're using Chrome (and I believe Firefox), which implement a "Happy Eyeballs" sort of algorithm that decides what protocol is going to provide optimal performance. Generally I find that if IPv6 connects and won't be glacial both err to IPv6 though.

Mac OS X implements the Happy Eyeballs stuff at the OS level, so it's tougher to diagnose V6 vs V4 issues because the OS will try to choose the optimal protocol for a given hostname based on (I believe) DNS lookup performance.

Yep, i understand, but, there are "solutions" from Microsoft about this, if somebody still wants to prefer ipv4 even though ipv6 is available.

That is the only reason, yes. (if everything was working fine, i wouldn't doing \ recommending this).

I don't want to disable it (IPV6), as, i might need to do some troubleshooting for them.

We will see.
