On one of my routers, when I do the show ip traffic command I keep seeing the "bad hop count " counter increasing. I also note that this router has gone (and still does) through 10 - 30 minutes of 99%cpu util (ip input)
Any idea on where I can start to trouble shoot this problem? My first thought was an application error where the ttl was set wrongly ... but I know no way to verify or check this ... hence the question..
Thanks in advance
P.S. I do not have multicasting enabled on any interface on this router
The bad hop count counter is increased when the router receives a packet with a TTL of zero. This might be normal if you have multicast traffic sent with low TTLs. Since you don't have multicast on this router, you can do a "debug ip error" on this router to determine what traffic is being discarded. Look for debug entries with the line "dispose ip.hopcount" in it.
Refer to the following url for more information on the debug ip error command:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
