Jay I did some testing on the following models and IOS versions and the results
were the same. If I source from a non-existent loopback they error out on
"ping" - If I source from a valid loopback they work OK
(C3640-JS-M), Version 12.4(25d)
(C3725-ADVIPSERVICESK9-M), Version 12.4(25b)
(C2600-ADVENTERPRISEK9-M), Version 12.4(25d)
>From invalid source:
R1(tcl)#foreach loopback {
+>(tcl)#200.0.0.1
+>(tcl)#} { ping $loopback so lo1 re 2}
invalid command name "ping" ^
% Invalid input detected at '^' marker.
>From valid source:
R1(tcl)#foreach loopback {
+>(tcl)#200.0.0.1
+>(tcl)#} { ping $loopback so lo0 re 2}
Type escape sequence to abort.
Sending 2, 100-byte ICMP Echos to 200.0.0.1, timeout is 2 seconds:
Packet sent with a source address of 200.0.0.1
!!
That's why we figured lo1 didn't exist on your 3800... Very odd indeed.

Yes, it's defined. On my 2800's, when I source a loopback that isn't there, it
still runs, but states it's not defined.
With the 3800, it stops on the ping command.
