Hello David
When a router does not receive any response from its echo requests sent out using traceroute, this is indicated by an asterisk: *.
When a router receives a response from its echo request from an intermediate router saying that the destination is unreachable, this is indicated by: !H.
In the first case, the router gets no response at all. In the second case it gets a response, albiet the response is from another router saying that the destination is unreachable.
Yes, you are correct, I will let Rene know to make the modification.
I hope this has been helpful!
