this is the real example of pathping command.

According to my knowledge:-

  1. Source to here column :- it tells about number of packet loss out of 100 send directly to hop

  2. Node/Link column. :- it tells about number of packet loss out of 100 which passed through this hop.

  3. | :- tells about link congestion.

my doubt is in 2nd image how hop 4 how Node/Link column is 100% packet loss?

how is hop 5 getting ping packet if there is 100% loss in Node/Link column in hop 4?

I know for security reason some router don't respond to ICMP packet. So this is the reason for hop 4 Source to here column have 100% packet loss but why node/link column is not responding?

what if | (link congestion) is 100% what will happen?

  • but why node/link column is not responding? Why it's discarding ICMP packet not addressed to it?

    There could be many reasons, such as access control lists. But ultimately, questions about networks you don't control are off topic.

    There's not 100% loss. Node 4 is not responding to pings addressed to it. But it's forwarding traffic to other networks.
