zcip left ip blank

[kate katty]

Hi ,

command is "zcip -r [ip] -p[prefix]  br0  [path]/zcip.script"
prefix is calculated from the netmask

zcip failed only once for me, I didnt know the exact reason then. And I'm
unable to reproduce the same, Could you please suggest idea that what if
zcip fails even though arguments are valid and  present.

I'm using busybox version 1


Regards,
