Hi All
I often encounter a strange output every time I trace route to a remote
destination.
I always miss one icmp packet in the last hop.
Something likes that
R2#traceroute 150.50.8.8
Type escape sequence to abort.
Tracing the route to 150.50.8.8

3 150.50.78.8 [AS 600] 36 msec * 36 msec
R4#traceroute 150.50.8.8

Those asterisks always appear (and delay for a while) every time I trace
route, from any router, any source to any destination, and every lab
that I have finished.
My router is all 2500 with 12.2 IOS,
Could anyone explain?
TIA

P/s: there is no problem when I trace route from my router to a
destination on Internet.
