TTL Expired in transit

TTL Expired in transit

TTL Expired in transit

Hi techies,

I tried to do a ping on one of the sites hosted at one of the servers in another network. But it seems that routing to the server has a problem.

Pinging server1.xyz.com [xxx.xxx.xxx.xxx] with 32 bytes of data:
Reply from yyy.yyy.yyy.yyy: TTL expired in transit.
Reply from yyy.yyy.yyy.yyy: TTL expired in transit.
Reply from yyy.yyy.yyy.yyy: TTL expired in transit.
Reply from yyy.yyy.yyy.yyy: TTL expired in transit.

Ping statistics for yyy.yyy.yyy.yyy:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

xxx.xxx.xxx.xxx is the IP address of the site that I see.
yyy.yyy.yyy.yyy is the router IP address that is facing the ISP's router.

I'm suspecting it could be due to the ISP's router facing the network's router. Or it could be the network's router facing the ISP router.

Has anyone experienced this before? Do you have any solutions or diagnostic tests for this? Thanks.


RE: TTL Expired in transit

TTL expired in transit is most likely a routing loop, usually due to mis-configuration, or if there is part of a network that is down.

Are these servers yours? Or is this another companies servers? Either way, I would check to make sure that everything is setup correctly. From the times I've had to help people with this problem I've found that for some reason the interface to the LAN where the servers are on the router has gone to Up/Down, usually caused by a fault switch or wiring.

Anyways, check it out and let us know.


RE: TTL Expired in transit

Thanks rburke.

I've also performed a tracert to the website(i.e. to the Server). and noticed that it hangs and repeated the looping between the network router and to the ISP's router.

The servers belong to my clients.

The switches are ok. Maybe I should change the connected port to see if it's ok. Thanks.

Any other suggestions, ideas, solutions? Thank you guys..
