Marko,

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.22.3, timeout is 2 seconds:

Ato,
What IOS are you using? I've never heard of "ping x source y" command,
neither have my routers :)
R2#tclsh
R2#
R2#foreach i {
+>#3.3.3.3
+>#4.4.4.4
+>#5.5.5.5
+>#6.6.6.6
+>#7.7.7.7
+>#} { foreach j {
+>#1.1.1.1
+>#2.2.2.2
+>#} { ping $i source $j repeat 3 }}

Here you go:
List of source IPs:
1.1.1.1
2.2.2.2
List of destination Ips:
3.3.3.3
4.4.4.4
5.5.5.5
6.6.6.6
7.7.7.7
tclsh
foreach i {
3.3.3.3
4.4.4.4
5.5.5.5
6.6.6.6
7.7.7.7
} { foreach j {
1.1.1.1

Hi Colin,
When you use the tclsh script to verify reachability, the outgoing interface
IP will be used as the source of the packet. My question is: Is it possible
to write the script in such a way to simualte an extended ping, where you
can define the source IP ?? If yes, then kindly ellaborate.
Regards,
Yasser
