Hi again, Hi Kaspar, tried EUI-64 approach, didn't help, here some RIOT debugging output,
---snip--- ipv6: GNRC_NETAPI_MSG_TYPE_RCV received ipv6: Received (src = fd59:7f5:2065:7622:27cf:f952:ab74:5912, dst = ff02::1:ffbb:e29e, next header = 58, length = 40) ipv6: handle ICMPv6 packet (nh = 58) icmpv6: neighbor solicitation received ndp: received neighbor solicitation (src: fd59:7f5:2065:7622:27cf:f952:ab74:5912, dst: ff02::1:ffbb:e29e, tgt: fd59:7f5:2065:7622:5855:4245:c8bb:e29e) ndp: received SL2A (link-layer address: 25:cf:f9:52:ab:74:59:12) ipv6_nc: Found entry for fd59:7f5:2065:7622:27cf:f952:ab74:5912 on interface 7 (0 = all interfaces) [0x20001428] ndp internal: send neighbor advertisement (iface: 7, tgt: fd59:7f5:2065:7622:5855:4245:c8bb:e29e, dst: fd59:7f5:2065:7622:27cf:f952:ab74:5912, supply_tl2a: 1) ndp: building target link-layer address option (l2addr: 5a:55:42:45:c8:bb:e2:9e) ndp: building neighbor advertisement message icmpv6: Building ICMPv6 message with type=136, code=0 ipv6: GNRC_NETAPI_MSG_TYPE_SND received ipv6_nc: Found entry for fd59:7f5:2065:7622:27cf:f952:ab74:5912 on interface 7 (0 = all interfaces) [0x20001428] 6low: KERNEL_PID_UNDEF ipv6: error determining next hop's link layer address ---snap--- I'm not quite fit with internals of gnrc ipv6|6low|ndp but somehow the stack cannot find a suitable router/interface to forward/send the message and gets this 'KERNEL_PID_UNDEF' out of the loop - which finally drops the packages and nothing is send. However as you can see above the NS from the RasPi is received, all IPs are correct and correspond with my setup (no byte flips or anything here). A response NA is build and put on the stack for sending, which fails.
