osx can't access [bbbb::100] but windows/linux can

[wumin1]

Hi git mates,

I manage to setup 6lbr on a raspberry work with cc26xx nodes. Everything act exactly as described in the tutorial except I can not ping nor access bbbb::100 website in any browser on OSX. However a windows or linux host in the same network can. I'm not family with IPV6. Why there're three inet6 address start with bbbb:: in en0 (see following code) ? What could be wrong, and how can I fix this?

ping6 bbbb::100 from OS X

>ping6 -I en0 bbbb::100
PING6(56=40+8+8 bytes) bbbb::14a2:3bbd:6ac:4926 --> bbbb::100
ping6: sendmsg: No route to host
ping6: wrote bbbb::100 16 chars, ret=-1
