ping fails for link local address( IPv6)



hi all,

i have configured IPv6 on linux machine. i can see the link local
address as an output for ifconfig, but when i try to ping to it i am
getting an error "argument invalid"


i sending the output of ifconfig and ping6 to loopback ipv6address
which is successful and to link local address which is failing.


output:
=======
