> Hello Riot.
> I was cloned newest version of RIOT and build gnrc_border[1] router example
> with ethos. Initially it was nice, i was able to ping between my PC and
> border router (2001:db8::ff:fe00:2b), In other board (gnrc_networking) it
> configure the global address automatically (2001:db8::ff:fe00:5). But when i

> So i'm trying to ping between border_router and other board using global
> address (2001), the result is same. But when I change to the local address
> (fe80), it ping normally so the local address is working and global address
> is not with my board ?.
> I was enabled debug with gnrc_ipv6.c and cc110x_rx_tx and I found:
> - At the first time ping gnrc_ipv6 pass the packet to 6lowpan as normally,
> the cc110x_rx_tx snd packet to 0, and border router send packet back to 1
> (wrong address expected = 5)?
> - Next time I ping gnrc_ipv6.c doesn't pass the packet to 6lowpan it say:
>  ipv6: error determining next hop's link layer address
> Please help, thanks.
> p/s hwaddr of border router is 2b and gnrc_networking is 5.
