Routing to public internet

[uasui]

Hi,

I try to reach the internet by pinging a public ipv6 address from a end device running Openthread through Nordic Connect SDK.
This does not succeed, as the device does not know how to route it and drops it.

A netdata show results in something like

Prefixes:
[ML]::/64 paos low fffe
Routes:
[PD]://64 s med fffe
[PD]://62 s med fffe
Services:
...

with PD being a globally routable prefix from my ISP.

How is routing intended to be set up here? Is this an issue with IPv6, border router or end device?

Configuring a default route on a ot-br-posix example as suggested in https://groups.google.com/g/openthread-users/c/BhWQiCRPBAg/m/H1RucT3vBAAJ previously had worked. Can I do something similar on the end device, in case I don't control the border router?

The border router needs to advertise a default route to reach an arbitrary IPv6 endpoint on the public Internet.

At the very least, the BR needs to advertise a route that has the same prefix as the IPv6 destination the device is trying to reach.

Thank you for clarifying these responsibilities.

And generally thank you for all the work you do, Jonathan. Your insights and knowledge sharing in particular is highly appreciated and inspiring! 🥇
