7 years ago To anyone interested, here how to get a working ping6 between two BR configured as NDP-ROUTER. I have used the 6LBR mode and named my bridge my6b to avoid messing with an existing bridge in my setup.

first PC routing rules:
sudo ip -6 addr add bbbb::1/64 dev my6b sudo route -A inet6 add fd00::1/64 gw bbbb::100 sudo route -A inet6 add cccc::1/64 gw bbbb::100 -
second PC routing rules:
sudo ip -6 addr add cccc::1/64 dev my6b sudo route -A inet6 add fd00::1/64 gw cccc::100 sudo route -A inet6 add bbbb::1/64 gw cccc::100 -
on the webserver page on [bbbb::100] / [cccc::100] IP configuration prefix fd00:: , length 64, address autoconfiguration off, manual address fd00::1 (first radio)/fd00::2 (second radio) 6LoPWAN context 0 fd00::

Hi, I am currently stuck with a problem similar to the one discussed in #153 and a little help would be a real godsend! I am using a couple of SmartRF modules plugged via USB on two different Linux Ubuntu PCs, and I wanted to use the radio modules to give network connectivity between the PCs through 6lowPAN using the traditional IP methods the likes of TCP/UDP etc. The final goal would be to use 6lowPAN to give to an Android hand held unit (HHU) -equipped with a CC2650- seamless network connectivity through an OpenWRT board -also equipped with a CC2650-working as the real border router.
I have configured both the 6lbr daemons as a NDP-ROUTER, here the 6lbr.conf file: on both PCs
I set the WSN/Ethernet addresses to
I added the routing on nvm.conf files: on PC1:
on PC2:
the nvm file is:
and this is the route setting on PC2 (PC1 has mirrored settings):
from the 6lbr.log I see the boot works OK and I can browse the webserver on both PCs
But still, as you can imagine, I am not able to ping6 cccc::100 from PC1/bbbb::100 from PC2! I tried using 6LR mode too with no luck.
Have you any suggestions? Many thanks for your help!
