Yes you're right, I actually see the prefix already configured before start RPL, I don't know what kind of magic is behind that but I will investigate afterwards. > * Start your border router application and tunslip6 (e.g. beef::1/64) > * configure beef::2/64 on interface 6 at the border router and > add beef::1 to the neighbor cache on interface 6 > (these steps are outlined in the border router README) > * add abcd::1 to interface 5 of the border router > * connected 6lr applications (e.g. the microcoap example) should receive > a RA that contains information about the prefix (abcd::/64) and > they configure a global ipv6 address automatically > * now you should be able to do a ping6 from/to your microcoap examples. > ping6 between nodes was already working, I tried the steps you propose and my problem about pinging from my PC to the nodes is still there. By the way, as the prefixes you propose are not the same for both the tun interface and the 6lr network, ping from my PC cannot be possible, but configurations with the same prefix don't work neither. I'm thought about communication problems with the UART interface, but my last tests were ok while sending messages using such interface. I will make more tests to be sure that the second UART is working as expected. > You might however follow the discussion in [1], because there might be > problems > with IPHC/NHC for this setup. > I read the issue but I think I'll be able to test when my whole network will be set up. > PS: You can use ethos [2] to reduce the number of UARTs for your border > router. > > [1] https://github.com/RIOT-OS/RIOT/issues/4462 > [2] https://github.com/RIOT-OS/RIOT/pull/4438 > > Best, > Cenk Thanks!
