Troubleshooting this 'TTL:Expired in transit' message

Unanswered Question
Nov 5th, 2007

Imagine from my internal network I ping a client IP on a DSL line, on the Internet. Then my ping reply is:


ping 192.168.0.3


Reply from 145.19.7.3:TTL expired in transit.


What would be the best way to troubleshoot this? Is safe to assume that the target 192.168.0.3 is not receiving my ping, correct?

It basically tells you the packet didn't get to the destination after maximum the hop count has reached. Do a traceroute and see whether the packets are looping around somewhere or it indeed cross the maximum # of hops?

Yes, there is a loop somewhere in this path. I did ping -i 255 and tracert expired because at certain it reached a routing loop, right? I will just notify folks responsible for that target network about the problem. Thanks guys!!

There's a routing loop. Router with IP 136.195.33.110 thinks the next hop address for destination 192.168.0.3 is 136.195.33.109 and 136.195.33.109 thinks the next hop address for destination 192.168.0.3 is 136.195.33.110. The packet keeps bouncing back and forth between these routers until the TTL reaches 0 then it's discarded and you receive the ICMP time exceeded message.
