Thanks for your answers, I'll try to change the IOS.
I noticed that the problem happens only when there are Out of Sequence packets (ICMP reply not received).
I've done again the tests, and and captured the packets with Wireshark between the two routers. I calculated the average with the values in Wireshark by adding 0 for each Out of Sequence packet, then dividing by the Number of RTT. And I got the average value displayed.
*** For example ***
10 ICMP requests are send.
9 received (ms) : 337; 334; 328; 337; 334; 328; 323; 333; 327. [values obtained with Wireshark]
If somebody has the same problem, I also tried the ICMP Path Jitter operation with the other router, a 2851 with an IOS C2800NM-ADVENTERPRISEK9-M, 12.4(22)YB8 (fc1), and I got the same problem. (The first used was a 2821)
I'll try to get a newer IOS, but not sure my company has one...
Edit March 29, 2012
Well, I tried the experience on :
-a 2821 router, with IOS C2800NM-ADVIPSERVICESK9-M, Version 15.1(2)T2 (not the last version because of 64 MB flash)
-a 2851 router, with IOS C2800NM-ADVENTERPRISEK9-M, Version 15.1(3)T3
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
