I checked the net/bluetooth/6lowpan.c of linux kernel 4.7.1, could not find this feature. This would be required to support the "Isolated Bluetooth LE Network" topology. > Is this not simple run some Router Advertisment Daemon, e.g. radvd on the 6LBR Node and then putting a PIO into the RA messages. Maybe a ULA prefix for your $SUBNET? Then you have the routing mechanism based on your prefix. Additional you could also add a 6CO to compress the used prefix. See forked radvd branch [0] which used a non-stable UAPI to provide access to 6LoWPAN stateful compression. --- for the link-local case I through it must be possible to access 6LN's over it's their link-local address. Example 6LN(A) <---> 6LBR <---> 6LN(B) so it must be possible somehow to have a connection from A to B by using the link-local address. But RFC7668 says: "6LN-to-6LN communications using link-local addresses are not possible." So I think it's simple not possible and you must do the shared prefix and this is what you want (I think I finally understand), but this is not the job of 6LoWPAN subsystem - you need to do right IPv6 setup. - Alex [0] https://github.com/linux-wpan/radvd/tree/6lowpan -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
