How to share internet to Thread Note by Border Rounter

[Giang]

Hi all,

I am building Border Rounter and Thread Network. I using SDK 3.1 and image newest for border rounter

I follow this link https://infocenter.nordicsemi.com/topic/sdk_tz_v3.1.0/thread_border_router.html

I using Raspi 3B + NRF52840 (NCP) + Ethernet connection for Border Rounter and NRF52840(CLI) for Thread Node.

I can ping by Raspi to CLI node and CLI node to Raspi. I can ping Raspi to 64:ff9b::0808:0808. But when I use CLI ping to 64:ff9b::0808:0808, not response.

I can ping by Raspi to ipv4.google.com but not ipv6.google.com . It return connect: Network is unreachable.

In tayga.config : 

tun-device nat64

ipv4-addr 192.168.255.1

ipv6-addr fdaa:bb:1::1

prefix 64:ff9b::/96

dynamic-pool 192.168.255.0/24

data-dir /var/spool/tayga

 

Ifconfig on Pi : 

And this local raspi : 

And. When I run sudo raspi-config. Wifi notify No wireless interface found. And I can't enable Wifi.

Please help me . Thank  !!!

Hi,

Could you attach the commands you are using and a screenshot of the log output as well?

Now I can ping from Node to internet via Border Router by ipv6 address, but I still can't resolve domain. Please show me advise. Thank

Hi Giang,

Are you sure you have ipv6 connectivity between your BR and internet? It could be that your internet service provider (IPS) does not support ipv6 with /62 or lower prefix addresses... This is a common problem, see this case here for more information.

You can also try test the following command from the BR:

ping6 ipv6.google.com

Best regards,

In raspi : I can ping 64:ff9b::0808:0808, I can't ping6 ipv6.google.com -> network is unreachable

In CLI Node : I can ping ipv6 local, can ping 64:ff9b::0808:0808, But can't dns resolve ipv4.google.com fdaa:bb:1::1 and can't dns resolve ipv6.google.com.

I have no knowledge of internet class.

So can you guide me step by step.

I really need it.

Hi Giang,

Can you try to ping ipv6 address directly, try this command:

ping6 2001:4860:4860::8888

If it fails, you don't have ipv6 in your border router. You should then contact your internet service provider company.

Best regards,

Marjeris

Hi,

I checked. I can't ping to ping6 2001:4860:4860:8888 , ping6 ipv6.google.com but can ping6 64:ff9b::0808:0808 and ping4 ipv4.google.com.

Can you share me key work for resolve this problem ?

Thank

Hi, if you have a PC (or other device with a modern web browser) connected to the same network as the Raspberry Pi, you can try to open https://test-ipv6.com/ and see if all tests there pass - that way you'll at least know if your network has IPv6 access to the internet, and then go from there.
