Samuel,


With the information provided I assume you are running EIGRP. The logging shows you that the connection to peer (neighboring router) has been destroyed, due to expiring of dead-timer.


The router has not heard from peer within the expected time frame and declares his neighbor dead.


If this event is intermittent you should use debug ip eigrp neighbor and/or debug ip eigrp packet. Look for reachability issues.

Is dead-timer a term of ospf?

Is hold time has same meaning of dead-timer?

Your understanding is correct. Dead time is used in the context of OSPF and hold time is the term used with EIGRP.


show ip eigrp nei will show the corresponding hold time for that particular neighbor. The hold time is set by the neighbor.


See the example below.


This router uses the default hello/hold time of 5/15 seconds. In the first output, the hold time of 11 seconds indicate it has to receive another hello within 11 seconds and if it doesn't then it will clear the neighbor from the EIGRP neighbor table. In the second output (which was taken a second later) a hello packet was received and R3 reset the hold time to 14 seconds.


R3#show ip eigrp nei

IP-EIGRP neighbors for process 1

H Address Interface Hold Uptime SRTT RTO Q Seq

(sec) (ms) Cnt Num

0 192.168.0.1 Fa0/0 11 00:13:58 573 3438 0 1

R3#show ip eigrp nei

Hope this helps!

Sam,


First and foremost, the message that you are seeing is cosmetic and should not affect any traffic or EIGRP behavior. It was basically a debug message that is showing up in log without you enabling eigrp debug.


The fix for this bug is in 12.3(1) and higher. So if you want to run a code with the fix, you can upgrade the router to 12.3(20) and this should fix the log message that you are seeing. Before you upgrade, make sure that you have enough Flash and RAM on the chassis.


I hope it helps.

Arul
