close this as Status Invalid?

I need to use several IPs on interface in Linux, and switch it, but it's not working.<br>

and tcpdump:

UPD: BTW, just tryed same thing on Ubuntu 10.04 with 2.6.32 kernel,
everything works good, and you even dont need to add "-I" to "ping"
command, it seams in my kernel (3.2.0) somebody broken this feature.
