Hello Faizan,

you can use ping with -I argument like that

 ping -I source_IP dest_IP

When I try that (on 14.1.2.3), I get:

 

bind: Cannot assign requested address

 

It doesn't matter whether the IP is a self IP, a float, a SNAT, or a VIP, the message is always the same.

 

There are no route domains except the default %0.

    Stan,

     

    I had the same problem, but I found it was because I was in a different partition than the one in which my source self IP resided. From TMSH before switching to BASH do a "cd /<partition>" to switch to the partition where your self IP is, then switch to BASH an use Jad's ping command.
