Sure See below:
Basics after a ping:
Router#ping ip 172.16.1.1 ?
data specify data pattern
df-bit enable do not fragment bit in IP header
repeat specify repeat count
size specify datagram size
source specify source address or name
timeout specify timeout interval
validate validate reply data
<cr>
Used:
Router#ping ip 172.16.1.1 source lo0 repeat 1 timeout 1
Then you Get Pinging:
!
Save you lots of time
I use a script like:
foreach i {
1.1.1.1
2.2.2.2
3.3.3.3
4.4.4.4
} {ping $address repeat 1}
This saves lots of time especially when you have problems with reachability.
