ping6 -I eth0 ::1 is not working in the busybox-1.13.4

[Gayathri Manoj]

Hi all,

I have executed ping6 -I eth0 ::1 (ping6 in  busybox-1.13.4). But not giving
the response. The same command working fine, if we are using ping6 in the
busybox-1.4.2 version.

Error Message.
-bash-3.2# ping6 -I eth0 ::1
PING ::1 (::1): 56 data bytes
ping6: sendto: Network is unreachable
-bash-3.2#

I am  able to ping if the interface name is lo.

-bash-3.2# ping6 -I eth0 ::1
PING ::1 (::1): 56 data bytes
ping6: sendto: Network is unreachable
-bash-3.2# ping6 -I lo ::1
PING ::1 (::1): 56 data bytes
64 bytes from ::1: seq=0 ttl=64 time=0.396 ms

The following command is also working fine. ie by using ipv4 address in
place of the interface name.
-bash-3.2# ping6 -I 43.88.101.207 ::1
PING ::1 (::1): 56 data bytes
64 bytes from ::1: seq=0 ttl=64 time=0.334 ms


Please let me know is this one is a bug or a built in behavior?.


Thanks and Regards,
Gayathri Manoj
